looking for 2-meter yagi
 

I have been looking for a 2-meter yagi, around 10dbi gain or better, that
can handle 100 watts for around $100.00.
I was looking at the hy-gain vb-28fm but I do not know anything about this
antenna?

Thoughts, suggestions ?

Thanks joe

Think I would feed the it though a gamma match and 1:1 balun, or a few
turns of coax replacing the balun ...

With aluminum rod and some thread cutting dies, a guy could craft his
own to handle light loads.

I have a VB-214 that was a major disappointment. The eyebolts that secure
the elements didn't last two years before they were all quite rusted.

When I tried to buy a replacement set, I couldn't get a firm price
(including shipping) from MFJ.

Here is how I fixed it (albeit with a lot of labour):
http://www.vk1od.net/VB214/index.htm . From that page:

The lessons learned:

* this Hy-gain antenna had a very short service life because of
corrosion of plated steel parts used in its construction;
* replacement parts were not readily available to an Australian
buyer;
* it took longer to manufacture the replacement parts to suit the
existing antenna than it would have taken to make an antenna of a better
design from scratch; and
* critically assess the maintenance issues (eg steel components) of
an antenna of this type before purchase.

I don't know if they have changed their construction materials, I won't
take the risk on another Hy-Gain.

But a smarter man might either buy a better antenna or build a better
antenna, depending on his needs and capability. I bought the VB-214
having just moved and my workshop was 300km away. Today I would build
one, but that depends on an individual's capability.

One could build an antenna from the ground up more easily than repairing
this one given the difficulty in obtaining spare parts, and use a better
boom mounting that either soundly bonds the element to the boom, or
easier, reliably insulates the element from the boom.

If Joe is interested in construction, Google around for articles
describing element attachment using heat shrink tube and hot melt glue
for an insulated element that outperforms poorly bonded elements.

BTW, the gain claims for the VB-214 seem on the high side, I don't know
if they are reliable, and the same issue may apply to the 8 element
version.

This is the problem I want to avoid, I could build my own but I do not have
the time as in the next 6 months or so I will be moveing to NC and most of
my time is used up in painting etc. the home I am in now, getting ready to
sell it.
I need an antenna that can make contact with some of the repeartes here in
SC. (as band conditions permit)
I can, at times, get into some of the NC repeaters on my coliner vertical
at 50'. I was hopeing with a good beam at 70' (from NC) that I could
increase the odds...
Still looking for a good 2-m beam

While over your price range you may want to look at the M2 antennas. They
make a 9 element beam on a 14.5 foot boom and a smaller one for somewhat
less.

http://www.m2inc.com/index2.html

I put up the 9 element around 65 feet with the ssb set of elements (comes
with 2 sets of elements and you use the set for the end of the band you want
to use). It may pay to spend a little more for a good antenna that will
stay up than to replace one in 5 years. The antenna elements mount through
the boom on the plastic insulators. If made out of the same kind as the KLM
or Rutlan antennas I have used in the past , they should hold up for a long
time.

Also don't forget to use some good coax. I used the Bury-flex type. I just
don't like the copper coated aluminum of the LMR 400.

Most likely, truth in everything you covered there Owen. And you are
correct, I have blown much money on antennas, but never had one work
better than those I constructed myself (and this was true even if they
did not work as well! grin)

I have had good luck with antenna construction. Ones own work,
attention to detail and use of excellent materials easily defeat those
antennas made with only a profit in mind.

Warmest regards,
JS

You may regret the beam for repeater work. I live in the Greensboro
area and have found that even a tower mounted Ringo brings up too many
machines on a given frequency. Just about any tower mounted antenna
will work into the Mt Mitchell machine and there fore SC!

The real wonder of it all is so many repeaters and so little
activity...

What you are looking to do is more effected by antenna hiegth than gain. I
live on the NC/SC border and 25 watts into a vertical will get me full
quieting into most reapaters within my horizon,. more power or gain doesnt
help much. The Mt Mitchell Machine ROCKS. Was involved in a ragchew one
night with guys from 7 or 8 different states at least.

A bit of a story here but after you read it, maybe someone can make a
suggestion on the best way to approach this.


Currently, I have a 2-m collinear up 52 feet, fed with LMR-600 The rig is
a yaesu ft-2800m at 65 watts.
When I move to Richlands NC. I plan on moving it up to around 80 feet,
maybe higher if $$$ permits.
Right now, I can only get into the 146.820 when the band opens up. maybe
once a week .( I am pretty sure it is in Wilmington but the antenna on that
repeater is somewhere around 1,600 ft, or so they say) but it does cover the
richlands, Jacksonville area.
There is no way that I can get an antenna up high enough (after I move to
the new QTH, to any kind of line-of-site to any of the repeaters here, near
Charleston SC. However, the whitehall repeater is about 500ft and the
greeleyville repeater is up about 900ft.
What would you all do to increase your odds of getting into a reapeater at
that distance?

Just go as high as possible? add a yagi or stack some yagis?

Pray to the DX gods?

Any suggestions?

Thanks joe...

Unless you are on a high mountain, anything over 100 miles will be very
difficult to work into the Charleston area. . If you do get your antenna
up high enough to work the repeaters over 100 miles away, you will probably
be very unpopular as you will probablay be keying up several other repeaters
, or if they are using subaudio tones it can still cause problems.

What is the distance to the repeaters you will be trying to work?
