K160Rx protection

Elecraft mailing list
Hello
My K2/K100 complain and wants to get on the air.
I plan to use the build-in K160RX antenna switch for a separate rx antenna, which is about 10m /30 feet from my tx antenna. Plan to run 100 W.
Tx antenna is a vertical. Rx antenna is a low (1 m above grd) horizontal dipole.
Do I have to install a rx protection curcuit on the rx antenna.
I do not remember doing so earlier, but have forgotten and want to play safe.

Thank you, stay safe and keep distance

Hans,

The K2 RX ANT is injected at the same point after the T/R switch and
before the Low Pass Filter, so any energy from the transmit antenna will
not harm the K2 during transmit, although it may add to the RF level
going into the LPF and be amplified by the KPA100.
