These antennas have been designed by Bob Archer from Torrance, CA utilizing concepts common to military aircraft and space vehicles. The antenna performance is superior to most in use today in private aircraft. The only requirement for max. performance is that the antennas must be installed in accordance with the installation instructions. These antennas are designed to be installed inside fiberglass or other non-conductive wing tips or tail caps of metal or other conductive material aircraft.
This Wing Tip Com Antenna is designed to fit inside larger fiberglass wing tips on metal (conductive that is) airplanes such as T-18's, RV's Bonanzas etc. But tuned out for the Com Band. The wing tips must have internal dimensions of at least 11"x24" and generally fit better on the bottom surface. The VSWR is normally less than 2.0:1 over a frequency band of 108 to 127 Mhz but could be higher due to installation factors.
Offered because of pressure from RV builders. Users report good communications at ranges greater than 50 miles. Should be installed so that the maximum height of the tip is utilized to get the most vertical polarization.
The Archer antenna typically mounts horizontally in the wing tip. Please consult vans forums for ideal mounting locations. The com splitter is available but it is special order. Contact sales for price and lead time for the splitter.
Yes, this antenna will work mounted vertically.
The SA-001 is for VOR nav, and the SA-001-A is for COM only. We have now added the current installation instructions for both the 1 and the 1A antenna, which can be located on their respective pages under the "Documents" tab. For 2 VOR installations, the best installation is one antenna in each wingtip, each connected to a single receiver. For COM, only one antenna should be installed.
This is not recommended by the manufacturer. The NAV and COM antennas, even while not being used simultaneously, affect the performance of the other.
