Tony-
Ditto what others have said. A dipole is the ideal antenna for a glass airp
lane. I put mine on the outside edge of my rudder post so that I can get to
it if I ever need to. I used an AAE folded dipole, which would be another
good answer for you, but the foil dipole as outlined in the book is just fi
ne. Be sure to use an SWR bridge to tune it and you will have no problems.
In my particular case, the coaxial cable furnished with my kit was garbage.
It had an aluminum shield, which is hard to solder to. You need high quali
ty 52 ohm coaxial cable. Some versions of RG-58 or certainly, RG-200 will b
e just fine. If you go this route, both the center conductor and shield sho
uld be multi wire copper, which means it is easy to solder to. Do not use c
able that has a single conductor center. It is prone to breaking with vibra
tion. Everyone tells me that crimp-on connectors are fine. I am sure they a
re, although I don't like them. I wouldn't even put a connector on the foil
. Just clean it well and solder the cable directly to it. The rudder post i
s an ideal location.

Subject: Europa-List: Coax Advice for VHF antenna.
Gidday,
Ive got a bit of a hybrid, a classic with a few bits of XS thrown in. For e
xample I've got a sternpost, premanufactured that I was kindly given, and I
am now wondering if this is the structure I should be attaching my vertica
l VHF antenna to the front of. Now I've got the Europa kit, with torrodes o
r whatever they are called, and a bunch of COAX. I am wondering if anyone h
as an opinion on the merits of building up this antenna or whether I should
just bin it and use the Z shaped Bob Archer VHF antenna that I also have,
and put it on the side of the fuselage? I don't figure it would hurt to giv
e it a try, but am unsure if the Europa one is worth building, and if so, k
nowing nothing about COAX fittings attachment and being a lousy solderer, d
oes anyone have any specific guidance. Thank you in anticipation.
