Planning antennae purchases for RV-7A. GNS430W (NAV/COM/GPS), SL-40 (COM), and GTX-327 (txpdr) are planned. Here's what I'm thinking:
1. CI-122 bent whip belly mount for the GNS-430
2. CI-121 top mount com antenna for the SL-40
3. Bob Archer AS-001 wingtip mount VOR antenna
4. CI-101 for the transponder
Questions:
1. Will the Archer wingtip ant work for glideslope or is a separate glideslope antenna required?
2. Is a separate DME antenna required? (Do I even need DME)?
3. Is a marker beacon antenna required? Is this where stripped coax can be used?
4. Any thoughts on the combo antennas which combine XM or GPS with a com function? These seem pretty expensive.
5. Debating a Ryan Howell "rypole" vs. a RAMI AV-14 belly mounted antenna for APRS transmitter (144.39 MHz). Will probably go with the Rypole for drag reasons - anybody using the AV-14?
Don't know much (ok, anything!) about antennas. Any comments appreciated.
