the deciding factors for your antenna system are the following stations:
WTSP-DT 10.1 CBS ST. PETERSBURG FL 272° 26.7 24
WFLA-DT 8.1 NBC TAMPA FL 175° 24.8 7
WTVT-DT 13.1 FOX TAMPA FL 173° 26.6 12
a uhf only antenna (cm4228) will not work for you because of vhf channels 7 and 12 see choice #1.
You will need a rotor to receive wtsp (see choice #2 for alternative).
choice 1 - with rotor
- a combination vhf/uhf antenna with rotor...winegard hd7082p (110" see picture below) or winegard hd7084p (131" better)
-add winegard hdp 269 preamp if you are splitting signal a few times (cm7777 and winegard ap8275 high gain amps not suggested at your distances).
-mounted on a 3' tripod with a 5' mast...you can cut off the top 1.5' of the mast for lower profile.
choice #2- without rotor, requires 2 antennas
-cm4228 or cm 4221 uhf antenna pointed to 272 deg for uhf ch 24 with a channelmaster jointenna antenna combiner for ch 24
-Winegard hd7082p or hd7084p pointed to 174 degrees for all other channels
-add winegard hdp 269 preamp if you are splitting signal a few times (cm7777 and winegard ap8275 high gain amps not suggested at your distances).
-the system would also need to be properly grounded from the tripod and from a coax grounding block refore the coax enters the home to a grounding rod...or if on the same side of house as electical/power meter, you may attach ground there.
-use 100% copper 60% braid rg6 coax swept tested to 2ghz.
