I was checking coax feed line loss for 30M using

http://ocarc.ca/coax.htm.

Just to keep it simple I plugged in the power as 100 watts and the SWR as 1:1 and the cable length as 100 feet.

Tandy RG-58 showed a loss of 24 watts (24%) while Beldon RG-8 showed a loss of 12.009 watts or about 12% for the same length.

Question: Are those losses reciprocal? In other words would a received signal be attenuated by the same percentage? Always wondered about that.

Thanks,
