KSPX-TV (ION) · Channel 29

Full-power stations are the main licensed broadcasters in a market. They may run the highest power from the tallest towers and are protected from interference, so they set the core of what you can receive.

At 1,000 kW effective radiated power, KSPX-TV runs more power than 79% of full-power TV stations nationwide (median: 273 kW).

Its antenna sits 445 m above the average surrounding terrain, higher than 63% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 62 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 73 miles with an outdoor antenna. That area includes 319 cities and towns in our guide with about 10,900,000 residents, as far as Campbell, CA (71 miles).

KSPX-TV shares its transmitter site with KTFK-DT, KXTV (ABC), KMAX-TV (Telemundo) and KOVR (CBS). One antenna aimed at this site picks up all of them.

The nearest other ION station in our data is KKPX-TV in San Jose, CA, 64 miles away. Viewers between the two can sometimes receive both.

ION Television is a commercial network built around crime and procedural drama series, with some live sports. It is carried free over the air in most large markets.
