Outside in this climate can be very tough to keep in tune. The way I am setup the rig is in the garage which is insulated and heated. The 90' of open wire line from the center fed 75 meter extended double zepp is the vertical twin feeders shorted at the feed point right where it comes in the garage. The pair of 150' legs are the top loading. 160 and 80 meter tuning networks are right there also so I still have a very effective HF ant. If I plan to go any lower in freq I would enclose that outside at the present line input point. The 90' tower is about 15 feet from this garage line input and is a straight shot to the garage line input point. Never have to go outside to change things and keep a close eye on what is going on. Have to realize to not get crazy and be stupid with the power into the ant. A KW input to the ant on any band is safe for the most part-Bob

Wow coils on the bench. Why aren't they
outside with a remote tap switch? I'd be afraid of the RF exposure
with them in the house. Also starting fires. Crazy stuff.
Happy Holidays,

Mike;
I have tried taking pix but they don't show much. The blue
flame arcs are thin looking not a bright blue. But they do
contain allot of heat as I put a piece of paper with it glued to
a insulated screw driver and it catchs fire instantly! Might
take a real dark room to see it better on a picture-I'll work on
it. The arc to a screw driver is 3 inchs long and hisses like a
snake! I got too close to one of the loading coils with my
wrist. Gave me a bad burn but didn't hurt real bad but took
three months to heal! It was on one of the first series coils
so voltage wasn't that high yet. My loading coils are setting
on the operating table here select them for 73 thru 500 bands.
