Cantenna resistor was some carbon film unit to reduce inductance that a wire-wound would induce. Only old gear regret of mine was misplacing a Martin Flash key bug during one of many moves in the 90's.

The Cantenna is simply a non-inductive resistor dunked in oil. I think the resistor was rated for 200 watts in air.

It had a few resistors, a diode and a capacitor to give a DC output measurement via a voltmeter.

No coils involved.

I built the Heatkit SB-104A half a century ago!? Some of the most fun I ever had!

?

Also built the SWR meter, the crystal 2m VHF FM xcvr and the 25W VHF amp, also for FM.

?

I learned so much building these Heathkits and I was so propud of what I was able to build.

?

I'm interested in replicating the Cantenna.? How is the coil wound?? How much power can it take?

In the 70’s, I built my entire station…Heathkit.??First it was??the HW-101, the HA-10 Warrior amp.??Warrior was just too big and didn’t match the 102, so I built the SB-200.??Not done yet….wanted more power, so?

You guessed it, the SB-220 was next.??Had to have the?Cantenna, so it was added to my kit building!??Welp, no AM in the 102, so the SB301/401 was next.??(The world of split frequency operations was soon discovered and quickly loved that capability!

Outside of the ham equipment, I built lots of Heath kits….Color?迟惫’蝉, multi meters, O-scopes, automobile scopes and tuners, weather station, digi clocks…Don’t remember all else, but there was a lot of stuff,??I loved building.

?

I still have some of the Heath stuff, but with the exception of my?cantenna, all the Heath amateur??gear is gone.??L

?

The automobile scope still works but no longer really needed with today’s cars.??I still have my weather station and digi clocks as well my?multimeters?(VOMs and VTOMs)?

?

Yeah..hindsight?is a bear….

?

Wish I still had all that ham stuff. They worked beautifully!

you know, it’s easy to say I never should’ve got rid of that rig, whatever that rig was, but back when, I always had to trade or sell stuff to be able to afford newer equipment,.
