All,
Off all the antennae Ive tried over the years (since '84 when the AOR2001 hit the scene!) to use on UHF airband, I think the biconical design (ie broadbanded vertical dipole) is the best performing, and that includes several manufactured antenna types which have proved a little disappointing.
I made some and really recommend them (if you are up for a bit of soldering and messing with bits of wire).
I had these pictures on the old site and one or two chaps tried making similar to good effect.
The inner conductor of the coax solders to the upper "cone" and the outer conductor to the lower "cone"
(The 2 cones must not touch. The supporting structure should be wood, or other non-conductive material)
Best regards
Alan
