As to making the antenna out of very thin wire; from my Nave ET days, a thin antenna element has a more narrow bandwidth. Since flarm uses a frequency hopping protocol (I think from 885 to 915 Mhz), thin may not work very well.


lower freq 902.20000000 upper freq 927.80000000

Source - FCC application for PFP (no application, or other
certification data, published for PFB).

We are all faced with fitting these things to legacy gliders of varying geometry and materials. The carbon fibre fuselage seems to pose most problems.

I hope glider designers in future make installation of transponders, Flarm and PowerFlarm etc. easier, without dead spots or vision impairment.

We have published an Application note for the FLARM antenna installation:
http://powerflarm.us/manuals-softwar...release-notes/

Deep link:
http://powerflarm.us/wp-content/uplo...e_ANTENNAS.pdf

Still a bit raw, but we will update it with more pictures and examples.

Looking at page 6, there is a much less offensive 1/4 wave antenna shown that Flarm folks say works well.
Any of you expert guys have an idea where we get on of these?
Thanks

Excellent,

How do I get one of the 1/4 wave whip antenna's shown on p6 of the Application Note? Who it the manufacturer and what is the part number?

There must be some company that builds a nice FLARM compatible 1/2 wave
length base fed antenna similar to the one in the following link.

Mobile Mark PSTG0-925SE
http://www.tessco.com/products/displ...13&eventPage=1
It is a 'special order' item, but as of this morning they have some in stock.

Note that the length and picture on the Tessco site are incorrect.
Actual length is 2 7/8 inch. Datasheet is he
http://powerflarm.us/wp-content/uplo...STG0-925SE.pdf

Don't bug the manufacturer (Mobile Mark) about these; they have a minimum order quantity of 250pcs...

Disclaimer:
This is not a product that FLARM has tested, supplies or officially endorses.
It will require the installation of a suitable ground plane and coaxial cables to work properly. Please do not ask us for individual support on this type of installation.

That being said; if installed well, this can be very slick...

I won't be buying powerFlarm until the antenna installation is as unobtrusive as my Transponder. Di-pole sticking up above the glare shield doesn't cut it. Figure out another way. You have plenty of headroom to boost the power and use a less efficient 1/2 or 1/4 wave antenna. PowerFlarm needs to step up and fix this problem.
