I'm curious about these. Where can you get them? ( I have browsed antenna areas on a number of web sites and I cant find them.... perhaps I dont know where to look!) Are they worth having in the first place? Push Up implies that you can loosen, raise, tthen tighten. Assuming this is true, what is the lowered length and the raised length? How high can they go without guying?(for this one assume that it might be bracketed to the house at 10'(back of the house) or about 17' ( front side of the house). I hope all this rambling makes sense... and thanks.
