Antenna Separation
Posted: Sun Aug 21, 2016 5:09 am
I recently got my SDRPlay and so far I love it, but I want to make this even better and use it as a panadapter for my FT-991 and FT-857D. Since both of those radios are 100W max, what kind of antenna separation is required in order to keep for damaging my SDRPlay? So far I have been disconnecting the SDRPlay when I TX.
At home I have a 1/2 wave fan-dipole 20/40m and I also have a 60ft EMCOMM II. The feedpoints of both antennas are only a couple feet apart but they are perpendicular to each other. Normally I switch between the 2 antennas on the FT-991, would it be safe to put the SDRPlay on one of these and the FT-991 on the other?
For the FT-857D I would like to use it while mobile or for NPOTA. I have a SuperAntenna MP1B and I also have a hamstick dipole that travel with me. How much separation do I need between these to keep the SDRPlay safe assuming a max of 100W.
I basically never go over 50W on either radio, but I just want to play it safe and plan for 100W out.
Thanks,
Josh
