Web Electronics made two rigs in its short life (1951-52). There was the
Clamper and Junior Clamper. As far as I can tell, it was never sold as a
kit.
One ran about 25 watts peak and the other ran about 40 watts peak.
Lots of these types of rigs "mobile 10M", "mobile 10/6M", etc. were
hitting the market in the 50's.
Lots of people wanted to cash in on the American dream of being your own
boss and making baskets of money.
Most of these companies lasted only a few years if even that long.
A number of these rigs got their initial exposure in either CQ or QST
mags. as a construction article.
