Tx Antenna Question

Over the weekend I managed to have a prop hit my transmitter antenna and
break it in half. Are Futaba antenna's on size fits all? I have a 6XAS that
I fly with, and this has put my other basic Futaba remotes out of
commission. What I'm asking here is, will the antenna off of the old boxes
work with the 6XAS?

When I di this last year and went to buy a replacement, the guys in teh
shop told me that they were indeed one size fits all.

The very important thing is the length, and the diameter affects tuning
slightly. Unlike receivers, the TX antenna is a critical part of the
overall transmitter tuned circuit. If the replacement when extended
looks exactly the same, and fits perfectly, then use it.

Otherwise they are cheap and the LHS should have several in stock (buy
two, one for next time) so why not just replace it?

Re: Tx Antenna Question

One size does not fit all as unlike other brands, Futaba use several
different lengths, thicknesses, bases <means of attachment> according to the
TX type e.g. local reference numbers =
4e+101 TX-ANTENNA-3PJ40
4E00101 TX-ANTENNA-3PJ40
91171 TX-ANTENNA FOR 3PG,3PGM,3PGE
91176 TX-ANTENNA 5-7-8UA/9ZA (91600)
91177 TX-ANTENNA-2VR-2PBK-4NBL-6XA/H
91178 TX-ANTENNA 3EG,4LG, 5NLP,6VA/H
91179 TX-ANTENNA FOR FM,GN-4-8J
91180 TX-ANTENNA-5,6,7FG-K/E
91182 TX-ANTENNA 3,4,5,6EN-FN-GN
91185 TX-ANTENNA FOR 2F,3F
91187 TX-ANTENNA FOR 7M-SERIES
91601 TX-ANTENNA-2CH-2CR & 2DR(ONLY)
92701 TX ANTENNA FOR 5U, 7U, 9Z
S020701 ANTENNA BASE TX 7FGK(S-10310)
rather odd that Futaba do not list the Antenna on their parts listing =
http://www.futaba-rc.com/parts/xrfutk30.html
nor Tower on their TX antenna listing.
Ask your LHS to obtain the correct item as whilst a similar unit may correct
length, it ,ay be to slim and flop around or fat and be to tight.

Agreed, but how many of the above transmitters are current 72Mhz models?

I can't answer for 72mhz, but pretty much all the current 35Mhz ones
seem to use the same antenna, and I think the 40Mhz ones. The 27Mhz
stuff is different tho - cheaper 'toy' sets with flimsier antennas.

Re: Tx Antenna Question

I suggest getting a "Rubber Duckie" antenna. Almost impossible to break. :-)

Re: Tx Antenna Question

According to:

http://www.futaba-rc.com/parts/futm5040.html

the same antenna, part# FUTM5040, fits the Skysport 4 (4VF), the earlier 6XA (3
model memory), and about 8 other discontinued 2, 3, and 4 channel radios.

But from where, pray, do you suggest getting a Futaba "Rubber Duckie"
aerial ?

Re: Tx Antenna Question

Yeah, but range test it religiously I have seen those result in less that
acceptable (to me) range. Something to do with the change in the E and H
fields. orientation and the final stage amplifier in the transmitter.
