I purchased a Leaf antenna (30miles range) and I'm pretty happy with it. I get 30 or so channels, though most are useless (doubles or spanish) but I do get the few local ones that I was interested in in HD.
I read online that by using an RG6 coaxial cable in place of the RG59 that's on the antenna, I can boost signal making it more reliable and to get more channels. I was wondering if that is true? If it is, how many more channels are we talking about?
RG6 causes less loss of signal than RG59. How much actual additional signal you will get depends on the length of the cable you use. You may not receive any additional channels if the gain in signal strength is insufficient to let your tuner find them. On the other hand RG6 is cheap enough that it won't break the bank to try it.
