[Icom] How to protect Rx Ant input?

[Ekki Plicht]

Hi list(s),
i want to add a relay in front of the Rx-Antenna input of my 756Pro, sinc=
e=20
this input is not protected (turned off) during TX, and I already fried m=
y=20
RxIn once.

Question:
What kind of relay should I use? I.e. which is suitable for HF use?
