Let me know if they work for you. https://www.theeuropaclub.org/owning/poh-and-checklists I will send you an email with one of the variants. Noting that each are unique to specific aircraft.

Hi Ron, I have the UMA transducer installed on the of the airbox on my 914 (see picture). No issues in the 10 plus years it=99s been installed.

The resonant frequency is the point at which you get the lowest SWR on the meter. I found the resonant frequency at 116.4 but still had a SWR of 2.4 (ideally you want it close to 1) so this is high. At our typical frequencies between 118.0 mhz and 138 mhz, SWR ranged between 2.7 and 3.6. I thought this rather disappointing although it might explain why my transmissions at the upper end (134.80) to ATC are rather difficult for them to hear. I did hook up a Bob Archer antenna which is a dipole and appears pretty simple with no apparent scope for adjustment. I was surprised to get a resonant frequency at 109.5 mhz with a SWR close to 1. At 118.0 SWR was 5.8 and at 138 mhz it was 6.5! I don't think it is going to work with readings like that. I guess the question is, what comm antennas have others used that have been found to be successful? I'm particularly interested to know the best way of providing a suitable ground.
