How do I verify the freq of my TX to make perect GP Patch?


Recommended Posts

Hi guys (and gals if there are),

I'm new to this but have a Trex600 flying with an HD cam and I'm about to go FPV when I mount the Tx.

I also just got my video glasses/goggles today :D

Ok, the question is how can I find out the exact frequency of my Tx found here:

I actually have a 1w Tx also but do not have a link for that. It's the same ranges though as it appears all these 900mHz units are.

The reason is that I want to be the most accurate with my dimensions for the GP Patch antena.

Thanks!

The frequencies that are selected with the switch are very stable. Just use the mfg's published values.

So, what you are saying is that if I use the correct math in getting my ratio correct for the GP at say 910mHz, then it will be good?

I just didn't know if anyone actually tested these and found the frequency to be off... so then you make the GP Patch accordingly to match the adiusted frequency.

Thanks
