or, put simply, I no longer deal with the extra length required of the
5/8 ... your mileage may vary ...

The advantage of a physical height (antenna length) *between 180 and 215
degrees (see previous post regarding the magic number being around 195
degrees) is improved take-off angle and reduced skywave-groundwave
interaction, not dramatic nearfield voltage increases.

Regarding Mr. Smith's comments above my experience and others is the
opposite. 5/8 is a much better performing antenna than a 1/2 wave for
local VHF and UHF communications. Well worth the effort to build a 5/8
wave antenna over a 1/2 wave. The 5/8 had some kind of series load coil
part way up the whip where the 1/2 wave match/compensation was done at
the base so the whip was solid. Sorry I can't more specific then that as
those experiments were many years ago.

Mr. Smith is still lost in space.

- 5/8 wavelength antennas do not require a ground plane, do they?

Dave here is a Picture of a . . .

CBers use 5/8 WL Ground Plane Antennas very often.http://cgi.ebay.com/_W0QQitemZ260334577278
* Elevated Vertical Element
* Load Matching Device
* Ground Plane Radialshttp://www.pacificaerials.co.nz/antInfo/antennaTypes.htm#3
*.
FWIW the 5/8 WL* does go 'mobile' as a Vertical "CB"
Antenna but it uses the Car's body as the Ground Plane.http://www.firestik.com/Catalog/FS2-FS5.htm
* They do require Tuning {Matching} for Transmithttp://www.firestik.com/Tech_Docs/TUNABLE.htmhttp://www.firestik.com/Catalog/FS2-FS5.htm

Some where I remember a 5/8 WL Vertical Element
on top of a 5/8 WL Vertical Mast {Grounded} as being
a very good Antenna : Mono-Pole ? Collinear ?

A tuner at the antenna is a much better setup. You are doing things

wrong.


He's right, too. My sloper is resonant but I still use a tuner to
protect the transceiver. I was going to use the Remote Autotuner but
don't need it. I get a decent match even on 160.

Actually, Telemundo is just the same old idiot, pulling the same old
tricks and attempting to appear as a guru to those possessing even less
knowledge than himself ...

That's our boy Telamon!

You ridiculous fool. You are the most complete brain dead example of a
sub-human which has ever been presented to me ...

You dumb twit. We don't care about transmitting.

We don't...?

Receiving is EQUALLY as important as the transmitting element in the
above.

Again you dumb twit, we don't care about transmitting.

We don't...?

Yeah, very sad of you to keep plonking and then continue to read me.

I thought this was your trick?

What a goofball.

Takes one to know one.

Hey, telemundo is a great man, in his own mind, leave him alone ...
humor here is sparse, he provides for a needed demand ... :-)

Hmmm, I can see how you are mistaken; but, brother you are mistaken.
telemundo would not even amount to a pimple of a decent trolls hoary old

But then, you know, he already knows that ... :-(

I don't know if I interpret that, correctly, or not ... however, I think
a 5/8 is a FINE performer ... I only complain when having to add the
extra length to a 15m - 20m and longer! Indeed, a 1/2 becomes
impossible, and quickly--but then, you already know that ...

At 6m and below (talking meter length), no problem!

I never even commented on where the placement of the matchbox would be,
and, as everyone knows, anywhere along the line you can place it. The
best place would be between the coax (feedline) and the antenna-
Right. That's because you are to stupid to understand a concept until
someone rubes your nose in it. This would not even occur to you until
someone else brought it up.
-that is, taking for granted that the match from your rig to the
feedline is perfect.

You are really worried about the match of 50 ohm coax to your radios 50
ohm output? Now that's funny.
IIRC - The Characteristically 50 Ohm Impedance
Coax Cable is 'only' 50 Ohms nominal . . .
Until you attach something to it.
SNIP

Nope. The cable itself has a characteristic impedance of some design
value. The spacing and size of the conductors along with the dielectric
constant of the insulator between them dictates the impedance of the
coax.

You are confusing the characteristic impedance of the coax with its
ability to be an effective transmission line. The coax only behaves as
an effective transmission line when both ends of it are terminated at
its characteristic impedance.

Telamon,

OK -restatement- The "Measured" {by You} 50 Ohm
Impedance Coax Cable is 'only' 50 Ohms nominal*
* Until you attach something to it.

-IF- You then attach a Transmitters Output that is
a Nominal 50 Ohms to one end of the Coax Cable
and then the 'other' end will still "Measure*" about
50 Ohms.
* This is what the Antenna will see.

However -if- You attach an Unknown "Z" Antenna
and Ground to one end of the Coax Cable; then the
'other' end may "Measure*" near or far from 50 Ohms.
* This is what the Transmitter will see.


That depends on the length of the transmission line.
