I wish i had MY old old camping catalog, thick thing like a phone book
back in the 70's you could get a residential style yagi that cranked down and folded up,
had a cranked on the inside like the bat wing, but looked like a house antenna when it was and being used
a friend of mine had one on a Kings Highway class A, got more channels and better TV picture any place we camped than anybody else
i don't know who MFG it, but i sure wish i had one
