Wow Sandbagger i haven't herd that name in a long time. (Devant special). This was a killer antenna back in it's days. I met my high school sweet heart when she was talking on her fathers radio. Her dad had one of these antennas and to my surprised when i went over to introduce my self he had a 100 foot push up mast on top of his house with that antenna on it. Yes, his antenna was 130 feet in the air and he lived on a busy street. See how much everything has changed, Don't try that to day or you might have some big problems. I never knew this antenna had that kind of matching device on it, The High Gains Penetrator was the one i was thinking about. Both these antennas look very much like the I-10-K interceptor. The I-10K was most definitely modeled after the Hy-Gain Penetrator. But he adapted the matching system similar to what was on the Devant special. Taking the best parts from the top performers to make probably the best 11 meter omni ever made. Shame they're so darned expensive.

But the I10K does work great, and so far has stood up to all the ice, wind and snow that normally destroy others here. Of course when I bought mine it was $259.

I did a little looking around and comparing the transmitting length between the Devant special made by Mosley electronics, Hy-Gain's Penetrator, The 827 Sirio ground plain and the I-10-K interceptor.
Devant special 19.500
Penetrator 22.80
827 Sirio 21.981
Interceptor 22.425
Interesting how the Interceptor is very close to the Penetrator antenna. Roadrunner

As mentioned, Jay originally used the Penetrator 500 and Sigma 5/8 antennas - he used to rebuild them. Then he designed the M5K (Mastodon 5k) which was basically a clone of the Penetrator. What he learned from building the M5K he put into the design of the I-10K.
