FW: Transmitter Antennas

Fri Nov 8 06:09:37 AKST 2002

Below is from AMA.. I guess the question is, is it illegal in any way?
Maybe FCC issues some kind of certificate to the mfg. of a radio that issues
approval of a radio given a specific antenna.  And if that antenna is
changed, the radio may be illegal to operate?  That's the only basis that I
can think of that would make it illegal.  Don't think I want to be the first
case though...

BTW, I'm the newest NSRCA member (joined yesterday).  Glad to be part of the
SIG! Chuck

Chuck, AMA's position is that what is legal is legal.  I only know of one
whip antenna that is currently type accepted or certificated with the
transmitter this is the JR whip.  I've not put out anything regarding this
in a long time so I'm not sure what Annmarie is referencing, but a few years
ago it certainly as an issue and she may be pulling something from that.  

In short, if not flying in accordance with the AMA Safety Code, which
requires compliance with the law, you may run the risk of not being covered
by insurance.  No one ever knows for sure though until a case is presented.

Last year there was this same discussion on the "8U" list. Annmarie Cross
forwarded an email from Steve Kaluf to that effect. He was very adamant that
this modification would void the AMA insurance. Everyone thought it was
funny because that month's cover of Model Aviation had some glider guiders
with Ducky antennas.

 Please elaborate.  The AMA special interest group for pylon racing
attempted to ban short TX antennas but failed to do so during a vote last
year. Kurt

Remember that the AMA says they are illegal and that nullifies your
insurance.

I would not recommend doing one on the 9Z because of the mechanics of how it
is installed. There are some issues of fitting the installation inside the
transmitter, but it could be done. Yes, we install them in the 8U's here at

Tony, does the same model R/C Duck work for both the Futaba 8U and the 9ZAP?
Is it an in-shop (at Radio South) job to install in the 9ZAP? Chuck W.

We use the R/C Duck antenna.   It is $24.95 and works very well.  Note that
there is a reduction in output power, but only a slight amount. Tony

Wanting to replace my stock antenna on my 8U with one of those shorter whip
antennas.  I have looked around the web and couldn't find one (Central,
Radio South, etc.).  Any tips on a brand / source?  BTW, if this is a bad
idea for performance reasons, please tell me that also!   TIA, Chuck
