I am trying to get back on the air. I have three questions.

1) How do most of you get coax from the shack to outside? I am in Villages with concrete block walls.

2) If I go through concrete wall with coax are there any recommended vendors who will do it?

3) What are the best stealth antennas for 160-to 6 meters? 

Thanks for any help. richard KK4TG
