I am using a bleed resistor (2 times 47k/2W in parallel). The resistors get
handwarm after a long QRSS session (at 350W RF), they consume less than 1W
(there goes another 0.01dB of my signal).
I tried a choke but even a 20mH choke affected the antenna resonance too
much and got pretty hot while transmitting so I trew it out.
For savety reasons the antenna is grounded when I am not QRV on 136,
especialy in summer.
