antenna is vertically oriented as is the transponder antenna. I am

250) and typically use the radio around class B airspace 50 nm out.
The main thing in any antenna installation is to keep the entire
system balanced at 50 ohms, using the correct co-axial cable and
proper 50 ohm connections.
Bob Archer's antennas are available from aircraft spruce or directly
---From Bob Archer in Torrance, California. I don't have his phone # with
