You could be running way too much power if
Your antenna tuner needs a switch this big
Just bought this off ebay for 80 bucks shipped from someone overseas. I intend to make a remote motor tuned antenna tuner/ matchbox / coupler and put it up on the tower. This switch will select inductance and will use a big vacuum variable for the capacitor. I've already got some of those
This will allow coax which is noise shielded to feed up to the box, yet allow "all band" tuning 'up there.' The problem with a ladder line / balanced line fed antenna now is, "it ain't balanced." This is because with metal roofs, neighbors, power lines, and all the rest of the junk, there is no possible way to actually "balance" a "balanced" antenna, ant THAT causes the feedline to pick up noise and trash
