Poly Rope or Bungee??
 

Over the next week or so I'm planning on doing some
tweaking to my random wire antenna outside, and
I came across something on either the net or in a book
that recommended bungee cord for an outside antenna
to relieve the slack during wind gusts. I was planning
on just keeping a standard poly rope, but I was wondering
what the group thought of the idea of a bungee cord.

I found a 4" pulley for about $5 at the local home-improvement
store that's sold as a laundry-line pulley. Even though it's
plastic (with a metal axle), it's tougher than it looks.


The weight is a good idea. It has an automatic tensioning device that
keeps the rope tied to the antenna tight all year round. We all hate
sagging long wire antennas.

JD,

Rope through the Pully.

Rope tied onto the Weight.

Figure your Rise-and-Fall movement and
tie-off the extra Rope at the Center Point
of this movement with just enough slack
allow the Weight to Rise-and-Fall with
the Movement of the Antenna Wire.

Having the extra Rope Tied-Off in this
manner acts as a back-up to the Weight.

Hmm.. I've thought about that, but I think that the
kids wouldn't go for having a brick hanging off of
a pulley on the end of their wooden playset, and
my wife would freak if I did that at the other end,
where our screened in porch is.

I may just keep it with the poly rope in pretty
much an as-is configuration for a while, and see
how it goes.

You got that right! I put up a 36' mast years ago and used that darn
polyproylene, and after a few years it started rotting.

Stay away from that stuff.

Bungee cords and sunlight don't get along. Works if you replace often
enough. A pulley and weight are better.

Wind isn't really a problem. If you have the antenna held by rigid supports
that don't sway, don't worry about it. The tensioning devices are to keep
the swaying of trees, used as supports, from snapping the wire.

Something else to beware of is plastic at the connectors. I got a
dipole some time back that had each side of the dipole and the connector
attached to a piece of plastic. In about two years the plastic had
cracked, and broken losing one half the dipole. I continued to RECEIVE
ONLY on the half that was left. Now the whole thing is down! I suppose
I'll have to put up another antenna of my own some time in the future.
There'll be no plastic exposed to sunlight.

For what it's worth, in 28 years, I've never had a wire break from the trees
swaying in the wind. I can't see the point in pulling them so tight that there
isn't any sag in the wire.

I use 1/4 inch nylon rope and if the rope needs to be replaced from UV damage,
or squirrels, then it's probably about time to do some maintenence on the
antenna anyway.

Good to know. I'm still rainbound, so I really can't
do anything right now anyway. At the rate the
rain has been coming down the past week or so,
the Ohio River will start flooding soon.

Got it.

I was going to suggest a bucket filled with the necessary
amount of sand - but being at a childrens swing-set, I can
imagine that wouldn't last very long at all...

Ha. Not with my kids. I was originally going to
hang one end off the top of their playset (it would
have given me an extra 20 feet of length), but then
I thought that my son would try to see if he could
hang from the wire. Therefore, I decided to attach a
pressure treated 2x4x8 piece vertically on the rear
of the playset (4 feet attached to the 4x4 support
and 4 feet above the roof of the playset) so that
I could get the antenna wire safely above his
reach.

I'm thinking of modifying the rope to attach to
a rope wraparound thing that you'd find at the
bottom of a flagpole (yes, I can use technical
terms) and reknot it every so often. That'll get
me by until summer, and I'll reevaluate things
again.

Heh. Can't find a url to show you.

Take two long pieces of wire, double over, insert each into one end of a
compression spring, bend all wire ends out and over the ends of the
springs.

Pull on the wire loops, and the spring compresses.

These are availible commercially.

Tying off the antenna will result in the antenna wire stretching, so you
will have to tie off more often than you might like.

The easy way to keep the kids off the antenna might be to borrow a fence
charger for a while. It takes a wife with a certain sense of humor to
not kill you afterwords, of course.

Or a wife with enough sense to realize kids have to learn what "Don't
touch" means.

Yeah, I know what you're talking about. Something
similar can be used on screen doors. I'll think about
it.

I couldn't agree more! The 1/4" nylon rope is the way to go, and the longwire
doesn't have to be tight as a banjo string, to work well. Bring a butane
lighter up on the roof with you, so you can melt the loose ends to keep them
from fraying. I finish the knot work by securing the loose ends to the main
rope with some small black UV resistant cable ties. It neatens it up, and you
won't have to worry about it for years. Good DXing to you, Gary, Illinois,USA.

Excellent idea..
Test different weight / Rope length combinations.. Sounds like fun !!
- ALSO.. have extra weights on the ground tethered to the weight / pully
hookup
for very violent gusts..

- Don't know how it would fare in Ice Storms..



Bungees don't seem to weather well, but will do for the short
term. You may also consider, instead of directly tying it off
at the far end, running the rope through a pulley, with two or
three bricks (or some other suitable weight) to hold tension
on the rope.

I found a 4" pulley for about $5 at the local home-improvement
store that's sold as a laundry-line pulley. Even though it's
plastic (with a metal axle), it's tougher than it looks.

I *DO* admire your optimism, but if your son is like the vast
majority of
boys... Well, like I said - I do admire your optimism! Remember when
you
were his age? Try not to let him see you chuckle if you have to
admonish
him.

Oh, he has it really bad. I know what I was capable
of (like unlocking a door with three locks and a hook
at the top of the door when I was 2), so I plan
accordingly.

Seriously, "looks" don't make it perform any better. Put it up the
best you
can and, if there's a chance kids might attempt something they saw
in a
Tarzan episode, think "safety". It's better to break off under the
partial
weight of one kid, than the weight of three or four (think about
it).

Hmm. You have a point. My son (who's 3, btw),
climbed out over the top of the slide on the swingset
last summer and hung there by his hands. I was
running out to get him, but I knew I wasn't going
to make it in time. He let go, fell about 6 feet, got
up, and yelled happily, "I did it!!"

Besides, if you are like me, and perhaps some others in here, as
soon as
you get it rigged-up, within a week you'll have "a better idea"...

I'm sure about that. Eventually some of the trees that
I'll be planting in the backyard will be big enough to
hang from them, and I've also been thinking about
trying to "recreate" a good Wellbrook type antenna
without spending $300+ dollars to get a new one.

I'm thinking of modifying the rope to attach to
a rope wraparound thing that you'd find at the
bottom of a flagpole (yes, I can use technical
terms) and reknot it every so often. That'll get
me by until summer, and I'll reevaluate things
again.

--Mike L.


You lost me with all that technical jargon {G}, but you may want to
make
your own cleat with a couple of large nails driven half-way in at
opposite
angles from each other, so they form a wide "V" (Or more
appropriately, a
wide "\ /"). That way you can adjust the width as needed to
accomodate
the loose rope. If you are really brave, after you make that cleat
you
could give the leftover box of nails and a hammer to your son (who
needs
"action figures"!).

Ugh. I can see that having problems. I've gotten
sprayed with paint when my son "helped" me
paint the rails of our screened in porch, and I've
gotten sprayed by Bug-b-Gone by him as well
(accidentally, of course, he thought it was a
water gun).

WRAPPING THE ANTENNA WIRE THROUGH THE INSULATOR :
Her is the Method / Process that I use to Wrap the Antenna Wire
Through the Eye (Hole) of the Antenna Insulator.
..
Fold over One Foot of Antenna Wire at the End going into the
Eye of the Insulator.
..
Run/Route the Folded-Wire-End through the Eye of the Insulator
leaving about Three Inchs outside / unused Main Antenna Wire exposed.
..
Pass the Folded-Wire-End through the Eye of the Insulator a
Second Time and Snug-it-Up to lay with the Main Antenna Wire.
..
Take the Single Tag-end of the Antenna Wire an place it
Perpendicular (90*) to the Main Antenna Wire.
..
Take the Folded-Wire-End (Two Wires) and the Main Antenna Wire
(One Wire) and TWIST all Three Wires together Counter-Clock-Wise
(CCW) like you are forming a Western Ubion Splice. Do this
until all of the Folded-Wire-End is used up in the Twist.
..
Now take the Single Tag-End Wire (One Wire) and Tightly and
Closely OVER-WRAP it Clock-Wise (CW) Around the Three Twisted Wires.
Do this until all of the Tag-End Wire is used up in the Wrap.
..
RESULT - You have Four Wires (2x2) in the Eye of the Insulator
to Distribute the Force and Ware place on it; and Gives it a
Double Bite. The CCW Twisting of the Three Wires and then CW
Over Wraping of the Single Wire Mechanically LOCK the Four Wires
into a Solid Joint.

Element these can work well for direct mounting to a build or
structure.

WRAPPING THE ANTENNA WIRE THROUGH THE INSULATOR :
Her is the Method / Process that I use to Wrap the Antenna Wire
Through the Eye (Hole) of the Antenna Insulator.
.
Fold over One Foot of Antenna Wire at the End going into the
Eye of the Insulator.
.
Run/Route the Folded-Wire-End through the Eye of the Insulator
leaving about Three Inchs outside / unused Main Antenna Wire exposed.
.
Pass the Folded-Wire-End through the Eye of the Insulator a
Second Time and Snug-it-Up to lay with the Main Antenna Wire.
.
Take the Single Tag-end of the Antenna Wire an place it
Perpendicular (90*) to the Main Antenna Wire.
.
Take the Folded-Wire-End (Two Wires) and the Main Antenna Wire
(One Wire) and TWIST all Three Wires together Counter-Clock-Wise
(CCW) like you are forming a Western Ubion Splice. Do this
until all of the Folded-Wire-End is used up in the Twist.
.
Now take the Single Tag-End Wire (One Wire) and Tightly and
Closely OVER-WRAP it Clock-Wise (CW) Around the Three Twisted Wires.
Do this until all of the Tag-End Wire is used up in the Wrap.
.
RESULT - You have Four Wires (2x2) in the Eye of the Insulator
to Distribute the Force and Ware place on it; and Gives it a
Double Bite. The CCW Twisting of the Three Wires and then CW
Over Wraping of the Single Wire Mechanically LOCK the Four Wires
into a Solid Joint.

So please tell me, how many S units improvement will one notice using a high
quality ceramic insulator for shortwave reception, over just tying the wire to
the support rope?

K9RZZ - Sounds like you aleady know the answer.
Care to share it with us ;-)

The general theme of this thread was a Mechanical Failure of 'cheap'
plasitic Antenna Insulators; and better replacements for them.

But as you point out - If you use a quality Plastic 'type' Rope and
"Tie" the Rope and Antenna Wire together - That will work also :o)

Doubling Over (Double Lay) and Twist together about Eight Inches of
the Antenna Wire and a Single Lay of Rope usually works well for a
"Secure and Lasting" Knot between the two pieces.

Oh that's easy to calculate. You get a S unit For every $ you spend on a
ceramic insulator.

Yeah, you are S-9 +20 dB here. That's how the S to $ conversion works.

Get some of them old Railroad insulators.They will last forever.Speaking
of that,an old buddy of mine collects Railroad things and some of his
Railroad insulators are worth a lot of money.

Depends on the water content of the rope and what it's tied to for
support. It would be most noticable in a humid climate near the ocean.
