Uhm, I would NOT use this for making an antenna tuner for a high powered linear RF amp, but it does work nicely for 200 Watts or less, preferably 100 watts barefoot. KI7AQJ ham radio, luthrie & custom guitar, bass, keyboard, acoustic guitar & hi fi amps. I can get my ATAS 1200 antenna working down on 80 meters using this, and that is at best a 40 meter antenna. That is awesome!!!

Oh, and NEVER use anything like this with a loop antenna. Those can spike into the 1000s of volts, and you should use a 6KV vacuum capacitor with a loop antenna, unless you are running QRP. (less than 5 watts) Breakdown in air should be maybe a couple hundred volts. You could try to buy some mica and cut it to fit in the air gaps.

Any knob designed for a 1/4" solid shaft that uses a set screw should work.

This would be an acceptable choice for a crystal radio.

You will need to wind a coil or two or three, or more. Do some math! I think minimum frequency is more applicable. You should be able to run up to UHF with this, and down to 40 meters or more, 7MHz. Maybe 3.5MHz. Almost no one tries 160 meters. 6 meters has been dead for months. (50MHz) AM broadcast is just below 160 meters. 550 KHz-1.5MHz. You can put a cap in parallel with this, and make it larger. There are lots of free calculators for RF on line. KI7AQJ

This variable capacitor works well. It's range is 15pF to 406pF on my LCR meter. It is IMPORTANT to know that the 2 connections are made between any one of the lugs and the actual metal body of the capacitor. I use alligator clips to connect it.

Parts arrived here in Aus earlier than expected and well packed. There was a minor issue with the overseas credit card but on the whole I'm glad it was flagged and checked. Glad to recommend as a supplier to anybody here in Australia looking for tube bits and pieces.

Will build a simple antenna trimmer for BC and SWL use. The variable capacitor arrived well packed. It has threaded holes for ease of mounting and should work out fine. This item used to be commonplace and inexpensive....oh well!!

These capacitors are very well built with a solid frame, nice smooth bearings and well formed plates. I’m sure these will work well in my tube transmitter for amateur radio.
