The boom is hard to locate.
The boom in 2" OD it must be homebrew too.
I can find 1-15/16 pipe but not 2".
I'm thinking mufflershop
Remember this is libtard land up here.
People dont build or fix shit themselves anymore so theres no market for it.
The junkies truck metal to the scrapyard so its cleaned out everywhere.

Jay - thanks for getting back to me. I went into town yesterday, and bought a roll of #14 enameled motor winding wire. Both directors and the reflector will use it. The driven element will use #10 enameled. The characteristic impedance of a 4-element quad is 50 ohms, so I wound a 1:1 balun to connect between the antenna and the coax. My previous antenna was a 2-element quad, and worked great until a storm took it down. That won't happen with this setup. Thanks again.

* 357 sorry ... not trying to hijack the thread. *
I phoned the motor places around here.
The one guy said he "used" to rewind motors and might have some #25, nothing like #14.
Like I said, its a joke up here, its easy to just order it from Bulgaria.

Take a trip to the dump. Look for the appliance area. Look like you are not a wire pirate. Take your plunder(washing machines old). It will be heavily enameled. Exacto.
Making progress.
I heated the pipe with a lighter and pushed to tubing flush at the bottom.
I may heat again and squish it a bit more for sealing purposes.
Need to get longer sparkplug boots
and I found a new boom. (Thanks VE7JBG)

Hello Larry fist day on this site, great to talk to you today 357 is gonna be a big stripper up here. Always good to hear you 73”s 88”s
Hello 357: I had one of those Avanti Antennas Switches back ion the 70's, it was electrically intermittent and I didn't want it to burn up my radio or linear, with that cheap sh1t switch.. So I got a better ant switch that was pretty expensive back then.
The great thing about being able to switch back and forth from Vert to Horz is many skip stations change there received polarity as the signal bounced off the atmosphere. Kind of neat to track that if you want to help shoot skip. You can also switch the polarity to sometimes drop off or significantly attenuate interfering noises or stations.

I used to have a Wilson Shooting Star and the ability to switch polarity was a great asset. Sometimes the best signal strength was on V and sometimes on H and sometimes you had to switch often within five minutes while talking to the same station. There were times when local AMers would deliberately try to jam us on SSB and we would just flip to horizontal and keep right on talking while the jammers signals dropped several S-units. people don't know what they are missing until they can switch polarity with the flip of a switch.
Ya I should have just got a good cavity switch but I got bit with the nostalgia bug.
I will be ok for my 756, if it is intermittent I'll get a better one, which I probably will anyway.
Its nice to have it though as a keepsake.

Hello CK and 357: Yeah the ability to go Vert or Horz is a big plus for tactual communications that seemed to always be there. We had a great time at it. Project Straw Dispenser, Channel X, Back Door, and many others one used his Vert/Horz Beam Antenna, fine tuning AM stations with a narrow IF Filter when jamming is happening, the variable attenuator, LPI (low possibility of interception) type antennas, parked behind some ones house.
The center photo of the Avanti Antenna Switch shows the outside wires very close to each other possibly not allowing the isolation you may want when switching back and forth from Vert/Horz. Suggest swapping the outside wires and making the wires shorter to reduce any coupling that is there. You don't want the Antenna Switch to reduce any Vert/Horz Polarity isolation the antenna can do due to a cheap stereo speaker switch. You could also add copper circuit board material to make you own cavity to add isolation. Or even use coax for the outside wires.
I have a old old Gonset G12 tube radio that is the garage radio as I keep an ear on the locals bad mouthing me when I am in the advanced state of the art research and development center, the garage. Talk about nostalgia, even with a old WWII Eisenhower type carbon mic.
