I live in the San Francisco Bay Area, across the bay up in the hills with Sutro Tower in plain view (14.3 crow-fly miles away). I'm using a family castoff Magnavox MANT300 "SmartAmplifier" indoor antenna. I hooked it up last year in place of the testy, ancient roof antenna and kept using it, because it performed better than the roof antenna (believe it or not).
But . . . I still have problems, especially in bad weather and especially with the two VHF channels ("real" channels 7 and 12 = virtual channels 7.1 and 11.1). Those were also the worst with the roof antenna, too.
Here is my TVFool signal analysis: http://www.tvfool.com/?option=com_wr...81a38df8c557d8
As you see, I have line-of-sight (LOS) views of the sources of all the channels I want to receive (green), although I wouldn't complain if I also had channels 23 (22.1), 36 (36.1), 50 (54.1), and 9 (6.1).
Although this is an amplified antenna, I have the amplifier-gain control knob turned to OFF. When I try to turn it on, I have worse reception on almost every channel and channel 12 (11.1) drops from 80% to zero on the TV set's signal strength meter.
The problem is that the antenna is very sensitive to direction. If it is moved slightly (say by dusting it), I can lose the sensitive stations (esp. the VHF stations). Also, in rainy or windy weather, I lose some signals.
The antenna is situated off the floor, on the southwest corner of the house, next to a window from which the broadcast towers can be seen. I have a Panasonic Plasma HDTV purchased in December 2007.Question 1:
Do I compromise my reception by using an "amplified" antenna even if
I don't turn the amplifier part on? (I usually have the power adapter disconnected completely from the antenna.)Question 2:
If I tried replacing this indoor antenna, what models would work best in my location? (Yes, I know I should be able to "use a paper clip," as posters are fond of saying. Yet, I obviously need more. I studied EV's lists on page one and, frankly, was overwhelmed. Perhaps that means it doesn't matter what I choose.)
