Antenna and amplifier advice for Port Isabel
The farthest main network tower for Port Isabel is KVEO-TV (NBC), 39 miles away with a good estimated signal. That is why we suggest an amplified indoor or attic antenna here. Skip that station and you may get away with a smaller antenna.
An amplifier only helps here if you run a long cable (over about 50 feet) or split the antenna to several TVs. Otherwise better placement does more. See the amplifier guide.
