After a bit of destructive investigation, the problem was caused
by a screwed brass stud - not dissimilar to the 3/8 stud at the
base of CB antennae, but slightly smaller in diameter.

When the base part of the radiating element had been screwed in
place onto this stud, instead of the base screwing onto the
stud, the stud had, in part, unscrewed itself down into the
plastic insulator, by several turns. Unfortunately (for me and my
friend) also in the base was a 4-turn loading coil which had not
taken kindly to being unscrewed by at least 4 turns, and had
deformed so that it was intermittently shorting to the ground
plane through the tarnish of the loading coil.


Sounds like you fettled a perfectly good antenna. I am surprised you have
not claimed "shoddy goods" and cast it into the bin.

You seem very cack handed for someone who claims to do model engineering and
home brew your own radio equipment.

Just at it did at Westinghouse, the truth is emerging. You can't write
software and you can't do hardware.

Back to shelf stacking in a supermarket.

Does anyone have experience of the antenna of the title, which came
with all 3 suppliers info included? I purchased it at Longleat about
5 years ago, but never got round to using it. Now trying to install
it at my friend's QTH to get him going

I've just spent a very frustrating afternoon trying to put
this thing up, and when it was up, it exhibited a resistance of
200 Ohm between coax inner and outer.

Assumption - error in soldering PL259 - no - still does it.


On 27/06/04 you posted the following:

"Apart from wave guide joiners, it is the maximum frequency of use
which is the main consideration - your N plugs are usable right down
to DC. and will, in fact, give a better DC than any banana plugs 'cos
a step function has infinite AC frequencies in it which are better
preserved by the N."

Perhaps the antenna manufacturers were following your theory, and had
introduced a 200 Ohm step-function to "better preserve the infinite AC
frequencies". HTH

Google is you friend. Unless you are a still prat like Gareth ;-)
