[CQ-Contest] LP SO2R with no filters?

[Pete Smith N4ZR]

I did this for a couple of years - my main antennas were on a tower 
about 250 feet from an HF9 vertical.  I was running over 1 KW to them, 
and 100 watts to the HF9.  Did no damage - what's that adage about God 
protecting fools and...?  If I were to do it again, I would put some 
protection in the RX antenna lines - if your transceivers have provision 
for bringing those lines out the back and back in again, it's easy and 
cheap to build something - like
