Wow.... This forum is great! I would like to thank everyone for all of their input.
I live in Leesburg, VA and I installed an Antennas Direct DB8 Antenna a month ago. I was able to get 36 channels with the antenna in a bedroom window and 30 channels with the antenna mounted beside the gutter on my roof. Some of the channels are, 4-1, 4-2, 4-3 (NBC), 5-1 (Fox), 7-1, 7-2, 7-3 (ABC), 9-1 (CBS), 14-1, 20-1, 26-1 (WETA), and several more. I was able to get 30-1 to 30-6 while the antenna was in the window but I don't get them with the roof mount.
I might be using about 75 - 100 feet of cable but I am going to split it for multiple TV's. So, I purchased a CM7777.
I am also using an old HD Direct TV receiver as my tuner.
Since I am getting the CM7777 (amplifier) and I will have to climb the ladder again, I would like to have a signal meter with me on the roof, so I can adjust the antenna without asking a neighbor watch my meter on the tv screen while yelling the strength to me. So, I googled and found this forum!
I found a DIGIAIR PRO Off-Air TV Signal Meter but I don't want to pay $125 for a used one. Is there another meter that will do the same thing? I discovered what an attenuator is but I can still use my HD tuner as a meter, but I want something portable.
The next question is for my mom (Which antenna should I buy). My mom lives in Western Maryland between Frostburg and Grantsville MD. She currently gets, 2 (CBS), 4 (ABC), 6 (NBC), 8 (FOX). 2 and 4 Pittsburgh stations and 6 is Johnstown, PA. I am not sure about channel 8.
The current antenna has been destroyed from the wind (40 mph+) and tree branches. I don't recall the exact details but there is a small black box on the antenna mast and there is another box that I assume is a boaster from the 70's plugged in to a wall outlet with an RG6 input and output. The TV picture goes out when I unplug this box.
tvfool dot com has this info for my mom... I don't know the meaning of -dbm.
channel | miles | degrees
2 | 78 | 318
4 | 59 | 316
6 | 49 | 13
8 | 36 | 350
I should probably aim the antenna at 344.5 degrees?
To find the mid point.
360 - 316 = 44
44 + 13 (degrees from 360) = 57
57 / 2 = 28.5
316 - 28.5 = 344.5 degrees
Should I get my mom a DB8 that is suppose to reach 70 miles or a Winegard HD 8200U that is suppose to reach 100 miles? She lives around a LOT of hills and there are mountains between her and Pittsburgh. We have always used the big antennas without a great picture and I don't know if a small one like my DB8 will be sufficient.
She will have about 40 feet of cable with one TV.
Since she does not get any channels when I disconnect the 30 year old boaster, I assume that I should also get one of those. Is there one that you recommend?
Is there an inexpensive signal meter that I can purchase to use for myself and my mom? Which antenna should I get for Mom? Which boaster should I get for Mom? From what I have read, the CM7777 wont help her.
