I had time to waste this weekend so I decided to try something. I was wondering how strong the signal would be from a station approx. 75-80 miles away. I took my indoor amplified antenna hopped up on my roof and connected that antenna to my voOm receiver. Strangely enough, the signal strength meter on the voOm receiver measured around 60-65(once had it at 68). I though to myself (maybe wrongly) that if my little indoor antenna was able to get that signal strenght, then a bigger, amplified, outdoor antenna may really do much better. If it would work, then I could look forward to ABC in HD. So, I went to my local Menards, bought a 51 element outdoor antenna, and a pre-amp. Got everything put together, got up on the roof.....and only got a signal strength as high as 55. Why was my indoor antenna getting a higher signal strength?
