antenna identification
Does anyone know of a site that shows the common types and locations of airplane antennas? It seems like this would exist somewhere, but I've yet to find the right combination of keywords to find anything with Google. Matt |

antenna identification
I have found NAV/COMM antennas are generally located at the rear of the aircraft, about two feet in length. DME frequency is about 10 times higher, so the antenna is 10 times smaller. Due to higher losses at these frequencies, they are generally located near the front of the fuselage. Most of the ones I have seen are shaped like a shark fin, but I have also seen small stubby ones an inch or two in length. The ELT antenna is easy to identify because it will be close to the ELT, and it is shaped like a generic whip antenna. GPS antennas are also small because of their high frequency of operation. They may look like a flat disk, or a cone. Many GPS antennas have the manufacturer's logo on them, so they are easy to identify. The marker beacon antenna looks like a boat at the bottom fuselage, but I am sure there are other variants. Glideslope antennas I have seen are shaped like shark fin, V-shaped, or a horizontal wire inside the cockpit above the windshield. If you look through any avionics catalog, I am sure you will find the large variations of antennas out there.

Have to read for locations, though: http://www.avionix.com/antennas.html Cheers, Kev |

I did a Kitplanes article about four years ago on just this subject.

Com antennae are aligned vertically. Nav antennae (vor reception) are
aligned horizontally. This is because the com antennae on the ground is aligned vertically and the nav antennae on the ground is aligned horizontally. So called "polarization". |

I'm just brushing up for the commercial oral and figure this is a likely question. I'm going to take a picture of our club plane and identify them all, but I thought maybe someone had already done that and posted a picture somewhere. Cheers, Matt |

Is your article available online or is buying a back issue of Kitplanes the only option? Matt |

I have an electronic file of every article I've ever written, which means
that I went all the way back to AOPA August '77 and scanned in the article I wrote about the TSOd Pencil on the IBM Selectric all the way to April 2007's digital pictures with the new Canon camera. In between there are Radio Shack Model II Scripsit articles I ported via RS232 to the IBM DOS WordPerfect, then finally to Windoze and MS Word. The ONLY one I'm missing is Feb 2001, but I'll make you a deal. Somehow get a valid email addy to me and I'll scan it and send you scanned PDF files. Howzat? (Is the a good address?)
