It is a KT-34A made by KLM. KLM is now out of business. If you need parts or upgrades for this antenna, visit...

Here is M2's version of the antenna.

By the way, Mike Stahl OWNS M2 and is the "M" in KLM. Mike designed this antenna and with KLM being out of business is now building them again, but with some upgrades.

This antenna does NOT have gamma matches and operates on 20/15/and 10.

Its worth $250.00 on the used market.

thank you Master Chief you great with the help and i just found the manual there are two 1980 and 1983 i got it, here we go

o man i have a lot homework now

Robalo,
I never had one but have listened to quite a few. They are very nice antennas. Not exactly the simplest things in the world to put together, but certainly not impossible and well worth the trouble.
Living in a place with a lot of high winds (just N. of Texas... hot air travels upwards you know), they were sort of a 'delicate' type of antenna, lots of 'joints' and metal in the air. That 'delicate' is relative, does not mean I wouldn't love to have one! Just means that care should be taken with them (lower in high winds if you can).

Ahem... if you should decide that you just don't want to mess with the thing, I just happen to know someone who wouldn't mind taking it off of your hands. He's very generous, wouldn't charge you for dispossing of it for you. Wouldn't even charge you for shipping. Might even buy a round or two...

I wonder if this antenna could be modified for 11m ? we tried today with negative results. if somebody knows the measurements can you please let me know? i would really appreciate it.

Yes, and NO. The capacitors were designed to work on three specific bands ONLY.

Get rid of the capacitors and add some aluminum, it could be converted to 11-meter, but it will take some work! Did you know this antenna has TWO driven elements? You could get it to work without having to re-space the elements, but it would be less than optimum.

If you want an 11-meter beam, buy an 11-meter beam!

I agree! Don't ruin a great antenna by hacking it for 11m.Use a separate 11m antenna.
