Right. I will test it as is then decide if the impedance matching is needed (more than likely). once everything is set, I will put some hot glue to fixe the helical in the acrylic tube. It is only about 1-1.5mm space all around. I think a little hot glue at the tip of the helial to the tube will be fine.
I assume the 1/4 turn you are talking about is the tin started at the base of the helical and continue for 1/4 turn, not starting at 1/4 turn?
yes, the shoot out won't be exact. we all have different equipment and environment. But, it is fun to just a have comparison. Any way, the longest distance recorded on OSD/ GPS wins. only Single helical and a planar skew for diversity, 200 mW vTx allowed though.
I will set up my long range plane ASAP for RTH to work. This would be my 1st time I may fly out of my radio/ video/ LoS range. I want to be sure the plane will come back on its own either by a switch when video signal is lost or when radio signal is lost and trigger the fail safe.
I was going to work on it today. but the allergy got me. It is the pollen season here. I can hardly see anything with tears in my eyes outside.
