| For me, a major souce of TVI has been rectification at the joints in 
| metal rain gutters.  The fix was to solder the joints.   

Indeed the 40 watt problem I mentioned was actually due to 
worn mountings on the 2/440 antenna support.  Forty watts 
on 20 meters was destroying channels 2, 4, and 5 with noticeable 
trouble on 7 and 13.  Shaking the mast would make it come and 
go.  After replacing the antenna support and installing the TV 
antenna 5 ft higher on a rotor with a 2/440 beam over it, then 
putting on a Radio Shack high pass filter, I can now watch 
any channel with an excellent picture while talking on all bands 
80-10m with the amp (30L-1) on line.  All coax cables, including 
the Ham feedlines and quad-shield rg-6 for the TV/VCR and 
stereo all go through the same hole in the wall.
