Hi All, We are installing a Flarm in our Aviat Husky A1 tow plane. For better Flarm RF performance it will be better to use a external Flarm FR antenna like this one: http://www.butterfly-store.de/en/Ext...+FLARM,i10.htm Does anyone have experience with the best position of a Flarm RF antenna on a tow plane? Thnx for you help.

Ruddh,

Craggy Aero LLC also has some antenna options.

I can also make the antenna cable to the length you require.

Thank you all for your input.
Next season we will be using a original Flarm in our Husky A1 tow plane (located in the Netherlands) with a butterfly display. Depending on our experiences we will later decide on the upgrade to a PowerFlarm with ADS-B. We already have a mode-s transponder with ADS-B out capability.

In Europe we have rather different results with the range of the Flarm RF signal.
Overhead dense populated area's the results of a Flarm range analyses go from average to poor, while flights over desolated area's like the high mountains of the French alps give excellent results.

Here you have a range analyses of a flight with a DuoDiscus with original Flarm plus dipole RF antenna overhead the French alps http://bit.ly/UbXQvu

This is a range analyses of the same glider with the same Flarm equipment during a flight overhead dense populated western Europe http://bit.ly/VQxBXQ

This indicates that the correct placement of a high performance Flarm RF antenna is very important
