Jenny, see previous reply. I used to need an outdoor antenna with a rotor system when I lived 50+ miles south of where I am now.
The Antop AT-400B sits in a second floor window directly facing the two “tall towers” in Awendaw serving the Charleston SC metro area and is inside the house. Of course I am only 11 miles away from both 2000’+ towers. My home is built like a beach house and 13’ above grade (18 above mean sea level) to the 1st floor, so that 2nd floor window is about 30’ above MSL. Perfect, and within 1° of being aimed precisely at the towers as well. As I always say “Your mileage WILL vary!”, it always does.
That antenna is connected to the Tablo Quad. I have an Antop AT-215BB “ClearBar” model downstairs connected directly to the TV, for now with my older Antennas Direct Eclipse multiplexed in using a “splitter” until my final VHF-Lo channel (7) moves to actual channel 24. Most splitters can be a joiner as well, but either way you lose about 3db signal strength. I added the 10db signal booster (“smartboos”) made for the 400B because I didn’t need it upstairs. Perfection…
IF you end up with an outside antenna, do yourself a favor and either find someone who knows what and how to do it right or hire someone - if you are not comfortable doing it yourself. I installed the 40’ pole and rotor back 30 years ago. It was a typical old school Yagi antenna with multiple elements. These newer Antop “Big Boy” models perform the same or better than old style Yagi models, and come in a roughly 30" x 10" x 4" form (75mm x 25mm x 10mm for anyone outside of the states). If you have VHF-Lo (true broadcast channels 2, 3, 4, 5 & 6 only) signals that are going to stay, consider the 400BV model. It has a pair of screw in bars that help boost those five lowest channels. VHF-Hi - 7 through 13 - don’t really need them. My 400B handles channels 7 & 12 here just fine.
