The peak reverse voltage rating of the diode is the limiting factor for the
RF probe.  A 1N34 diode should be fine for power measurements of up to 25
watts across a 50 ohm resistive load - it will make little difference
whether connected to the antenna jack or the dummy load.

For higher power levels, a higer rated diode could be used or 1N34 diodes
could be used in series - the low voltage readings will be more inaccurate
if that is done.

A coax TEE adapter is one easy way to connect the RF probe to the coax
center conductor.

I did R1 adjustment during lunchbreak using RF-probe and got it about right.
I will check cantenna resistance afterwards and re-adjust if necessary.
I was worried about breaking RF-probe, but now I believe I can connect it
with dummy load and can't connect it directly to antenna jack.
