Installing the Archer VOR/ILS Antenna

I've got the Archer VOR/ILS navigation antenna match drilled to the left wingtip. It's the 8th and final antenna for the airplane. Here are Wikipedia links to VOR and ILS navigation. The information the antenna receives will go to the Garmin 430W to be use for navigation. VOR systems (VHF Omni Directional Radio Range) are still active but are being made obsolete by GPS. The ILS system will probably remain in use longer but they're also being replaced by GPS. ILS (Instrument Landing System) requires transmitters at every airport that must be calibrated and maintained whereas the GPS approaches don't. The other 7 antennas in the airplane are 2 Com, 2 Gps, Transponder, ADS-B and ELT.
