 Hi Alfio



 I am planning on doing the same do you have a drawing with the required dimensions on.The drawing I have dose not have the dimensions. 	


 Here's the data as published by Van's Air Force many moons

 ago.

Bob,

 Thanks for the Sunday surprise (VOR antenna diagram).  Looks like I may be building "a spare VOR ant" for the Lancair, as well.  

  

 I have not forgot to scan and frwd that  flexible COM ant drwgn & desc. Tonight.

 Regards,

 Mike W.

cheers mike and bob

  

 Dose the L angle length have any affect on reception as it just says convenient on the drawing.

   That piece is a mounting bracket that fastens

   the antenna to the tip-rib. It's dimensions have

   no appreciable effect on performance as long as

   all other dimensions are not altered.

   What does the tip-rib look like? Keep in mind that the

   Bob Archer VOR wing tip VOR antenna was designed for

   RV's . . . aluminum wing with aluminum tip rib . . .

   and a Fiberglas tip cover.



   The antenna is a highly distorted, quarter-wave radiator

   with a gamma-match feed line attachment. The quarter-wave

   antenna needs to work against a substantial RF ground. When

   the antenna is up in the air, ground is provided by a suite

   of "radials". On an airplane, the 1/4 wave comm antenna is

   grounded against structure or the aircraft's skin.



   If the proposed installation is not onto an aluminum airplane,

   the antenna's performance versus that which has been demonstrated

   on RV's (and other metal airplanes) is degraded. Too much? Don't

   know without trying it. But if it's a 'spare', maybe performance

   isn't a big issue. Just be aware that it WILL be different . . .

   your in-flight observations (perhaps being able to quickly switch

   between antennas) would be VERY interesting.

Bob,

Do you have dimensions for an Archer-style comm antenna for composite planes?

   No. In fact, the dimensions for RV wing tip VOR antenna were

   published in Vans Airforce newsletter. But from the description

   I deduce that it's the same design as the VOR except trimmed

   for the higher frequency. It' wouldn't be hard to craft one.



   Of course, it's still primarily horizontal antenna but certainly

   would perform better than a rubber duck in the cockpit on a

   hand held. Just shorten the length values by 11% to get you

   into the Comm frequency range.

   It occurs to me that you might be asking

   about the antennas that go into the vertical

   fin. I've not seen any of those.
