Back when I found one like this - http://www.newegg.com/Product/Product.aspx?Item=N82E16833997212
If I recall it was only about 45 bucks. from a company that I no longer remember their name (input welcomed) who was located in Florida someplace. Never had a problem once I got the VHF and UHF and it all lined up on a 10 feet boom. Had a downeast microwave pre amp on it.
