Thought to do it because of news on various stations in various cities get posted here sometimes..
Just sharing what equipment is good since I researched it a long time, I've had it since we "went digital" ... sure beats only getting 1 channel (Now I get about 90, varies between 84 and 112 channels depending on weather, high pressure is usually best)
Winegard Amplifier model AP-8275
Amplification Gain: VHF 29 dB / UHF 28 dB
(Good signal to noise ratio on this amp too)
Wire/Cable/Coax RG-11
RG11 has a 14ga inner conductor whereas RG6-QS has a 18ga inner conductor, so the loss would be greater in the RG6. The loss for RG6 is about 6db per 100 feet and the loss for RG11 is only about 4db per 100 feet (Rooftop mount 15' over the roof probably only needs 50' length, so halve that loss to about 2db total for 50' RG11)
Antenna
Winegard HD8200U
5 to 14.2 db gain over dipole

Rotor
I used Channelmaster model 9521A wireless infra red remote programmable so I can use the channel number to turn the antenna to whichever city Programmable 1-99 and also you can just enter the degrees, or step up or down.
Mount and masting
I used a 5-foot tripod, (a 10 foot tripod might be better,) but with 6 guy wires it held up fine with winds over 90 mph that ripped peoples' roofs off all over the city and knocked down at least two brick columns.
I used 1-1/2" EMT conduit for a mast, with the rotor and antenna mounted on a short section of 1-1/4" EMT conduit at top.
Guyed at the rotor, and halfway down again, 6 guy wires, 3 at each level.
I normally get
Any time of day or night
Austin
San Antonio
Temple
Killeen
Waco
Llano
Fredericksburg
In the morning, every morning, I get:
Houston
Bryan College Station
San Angelo
Often:
Corpus Christi
On "weird days" I get
Shreveport,
Arklatex,
Riuidoso,
Abilene
Dallas
Longview Tyler
and lots of Stations giving the temperature in Centigrade instead of Fahrenheit
I'm not bothering to list the super strange days I got Mississippi etc.
I'm about 65 miles or so north of Austin, and before "digital" ... I only got one channel on an antenna
Now, I canceled dish and cable, why pay more to get less (I told them that and they cracked up laughing)
My brother pays over $100 a month for his TV subscriptions, his wife and daughter come to my house when he's at work to watch TV over the antenna. He wishes his picture was as good as mine, every 6 months I have a spare $600 for a new gun

Obviously there is "some" programming "duplication" but some cities run a program at a different time slot than another city does, and Fox in one city s different than Fox in another etc.
And there are LOTS of channels in "some cities" that "other cities" don't have. We like to watch BYN or the Asian channels from Houston in the morning, my niece watches cartoons in San Antonio. I like to compare weather channels. THIS in Waco plays TMZ while THIS in San Antonio has Bat Masterson in that time slot.
Anyway, just sharing what equipment is good since I researched it a long time, I've had it since we "went digital" ... sure beats only getting 1 channel (Now I get about 90, varies between 84 and 112 channels depending on weather, high pressure is usually best) (Not counting analog stations from Mexico I get too since analog signals are less congested too now)
I have no relationship and don't benefit from any company mentioned above, but it's what I use.
Misc:
There is a channel 3 Kiii in Corpus Christi
There is a channel 3 KSAN in San Angelo
There is a channel 3 KBTX in Bryan/College Station
But all three 3's show up. You get used to it.
There's a channel 25 KXXV in Waco
There's a channel 25 KAVU in Victoria (and KMOL 25-1, 25-2 ...subchannels etc)
but you get used to it.
