Antenna install time to switch to the W7FG dipole. How best to maintain the feed-line impedance while getting the spreaders through?

Does anyone have any of the old 'porcelain bowl and big ass bolt' wall feed thrus they can part with? That way I dont have to cut major holes
in the drywall or outside wall and shove yank 100 ft of spreaders and wire thru.  Just cut the first few feet of feedline and attach to tuna and feedthrus. Connect the rest outside of house.

is there a supply of these I can buy somewheres? Anyone got 2 of them? no luck on a search so far, no luck on ebay, but maybe I'm not using the right words.

Send your  address and I will get some to you. I do suggest some plastic tubing to insulate allthread and keep it from contacting any foil on your insulation. I lit my shop on fire one night and it was a real challenge putting out the fire inside the wall.

station is coming together. everything is getting fixed, built, etc. not as fast as I'd like or used to be able to do, but it's getting there. It's also having the side effect of getting me more in shape as I do more outside stuff. So, as they say, It's all good!1one  Cheesy

I have a big pile of glass and ceramic feed-thru insulators. Big bowl type, bee-hive, plain cone style,  small bowl, you name it.  Most are missing the threaded rods, washers and nuts; those are easy to find. I should clean  'em up,  (put them in the dishwasher), add the threaded rod, and hardware, and also add some gasket material too.    Once I've done that I will put them up here for sale and on the various e-lists.
