Do a ground connection at each end of the coax. Use whatever you have on hand.

ive seen 1kw out but it is VERY hard on the tubes. It also weighs more than my mother in law. Its a huge case. I hated mine. reliable box though.

CB goes to the motor Maul input. Never put anything more than the radio into the motor Maul

To be honest that's probably the neatest looking sweep toob box I've ever seen.. to my untrained eye it just looks fairly neat.

7.5ft of 75 ohm 84% coax as matching section.

Whoops. So 12.33ft+ 12.33ft + 6.165ft + 6.165ft

Ok so 12.5ft on the tall sides, 6ft on the top and bottom.

I found a formula that says 1005/freq. So that comes out to 36.94 feet. I guess 2:1 for the rectangle shape would be ok? Feed it from the side for vertical polarization. How do i calculate the 75ohm coax feeder? Just use the vp of the coax and calculate a 1/4 wave?

Ive been wanting to play with this for years now. I think im ready. Lol. I think id feed it from the side to get vertical polarization right? That article doesnt give formulas for length or proportion etc. should i just use the available formulas for antennas of wire for a ful wave? Could i use...

I worked on a swinging choke supply. It was 1.2a and the choke was a peter dahl marked 2-4hy. The choke was literally 70%the size of the plate transformer.

Maybe some greybeards on here remember when choke input power supplies were the norm. Every amplifier had them. The wisdom that was preached is that they offer better regulation. I worked on plenty of amplifiers with them both large and small. The largest supply I've ever used with a choke input...

I provide a manual for my amplifiers. But I'm definitely in the minority.

This is why i cant find the heart to work on these things. I think it's absolutely amazing that guys are out there keeping all these old amplifiers running, but I will say that it's definitely a labor of love.

Use a footpedal.

Here is his "current" flyer if anyone is interested. It takes me back to a time before I was around to remember it.

Well, im not saying that one way or the other. They tune, they work, they are safe with big watts. I am happy he still is around. Its cool because hes been doing this for decades and hes a piece of the old school.

Hey everyone. I was able to answer my own question through a friend of mine. He's really old now and he's still kicking but he hasn't been building a lot. But if anybody needs his stuff he still got stuff. I'm glad to see another person didn't get claimed by time. His number is 1 (716)...

Anyone know if Lee is still in business/ building antennas?

Why mess with it?

Maco v5000, shockwave, colossal, mr coily, or any metal sirio antenna
