Understanding that outdoors would be preferred...
If I mount the suggested UHF antenna in the attic *clear of all the metal surfaces,* is there a rule of thumb that can be used to tell if I need an amp? I ask because the cable run required to get my antenna on the other side of the duct work, etc. would be quite a bit longer than I have now. Also, I assume RG6 would be fine?
Thanks again.
Here is a simple test to determine if an amplifier will help. http://forum.tvfool.com/showthread.php?t=13646

RG-6 is fine. There's no reason to pay for quad-shield. For planning purposes, RG-6 has about 6 dB of attenuation at the highest UHF frequency. VHF loss is roughly half that of UHF. Here are examples of how to calculate net noise margin. http://forum.tvfool.com/showthread.php?t=109
