Just an update for anyone following this thread. I tried the pvc lower half
with good results. I just did a very loose spiral of copper wire around the
pvc. I was wrong on a couple of things, though. The antenna in the picture
has 12" of copper pipe at the bottom, not 18". The pvc section was 18".
Anyway, there was no difference in performance but it's still not flexible
enough for the trunk mount. The other thing I did was compare it to a
trunk-mounted 3 ft. antenna by antenna specialists. The 2 signal reports I
got showed that my antenna won. The numbers I got from 2 people in different
directions were 5 and 2 db on my antenna and 2 .5 and 1 on the Antenna
Specialists. It's up rather close to the rear window. I wonder if either
antenna would do better closer to the back of the trunk.

I have constructed a homeade antenna that is mounted on a trunk-lip mount

on
a Nissan Sentra. The bottom is 18" of 1/2" copper pipe with a 3/8" theaded
adapter soldered in the bottom. There is a 9" long peice of pvc with a 2"
diameter 6ga. copper coil around it. Then there is 4" more copper pipe

with
a 3ft' stainless tip on top. The problem is that it would be too easy to
bend the trunk with copper pipe. I thought about a spring but then the

whole
thing would bend too much when the trunk is opened. If I move the coil

down
below roof level, the SWR goes way up. I thought about using pvc for the
lower part but I can't quite figure out how to construct it. I may take

some
pictures of what I have. Stay tuned......

Many times...........even tested them.



Sorry your tests results were debunked by Frank in the xterminator
thread, you are a voodoo tech


Frank never tested any of the antennas. Frank as well as you still
believes the earth is flat.

Yeah, if you really want to improve the efficiency of your antenna,
bend it over and put the high voltage node close to a large mass of
metal. LOL.


What do you think happens when you drive down the road with a coil antenna,
the whip folds back and almost touches itself.


Well mine doesn't and a decent antenna would have a stiff enough
whip not to do that. He was talking about bending it over like the
"Barney Phife" mobile.

I have tested many antennas , have you?


Yes, very many. I thought I was responding to I Am Not George.

Too many Georges around here to keep track of..
