Default What is the range of a terrestrial repeater?

I was just wondering what kind of range one of these terrestrial repeaters.
There should be one less then 20 miles from my house.
Yet, I get no signal from it.

It varies. Based on power, antenna gain, height of the antenna and local terrain. Rule of thumb would be about 5 miles, or less. They are meant to fill holes in reception from the satellite, not "broadcast" like a full radio station. If you're beyond roughly 5 miles, then I doubt you'd get much terrestrial repeater signal.

Acording to this it's a 7.000 watt repeater.

Also depends if the antenna is directional, or not. And if it is directional, what direction it's pointed, and what its beamwidth is.

HomieG, I live in Burbank, CA (right by the BUR airport if that helps) which is just miles West of Glendale which I believe is the location of my closest antenna. I can't pull up the info on the site listed above because I use a watered down browser and I wanted to see what info you could give me regarding that location, such as area of tower so I could go see it, how many watts, directional or not and so on (if you have the time in the next couple of days).

Thank you so much, your fan ever since that post you made to the guy with the antenna on the dash.

-Ryan

PS, did you call the Stern show and use the name "Homie" in the last week or two?

Hi Ryan - - - I have a fan base. Kewl! No, I didn't call into Stern.

There appears to be a repeater in Glendale. Pretty low power. 80 watts EIRP. Two antenna orientations:
Sector 1: 70 degrees, +/- 40 degrees (meaning the beamwidth is from 30 to 100 degrees, i.e. North-Northeast to East)
Sector 2: 330 degrees, +/- 40 degrees (meaning the beamwidth is from 290 to 10 degrees, i.e. from about due west to about due north)

From the dogstar link:
"This repeater is located at coordinates of 34.154956, -118.255014. The height of this repeater is 80 feet." Plugging those coordinates into Google maps, the site appears to be just south of the intersection of Ventura Freeway (134) and Brand Blvd, between Brand and W. Doran Street. Appears to be several buildings there. The height of the repeater is 80 feet, so that would mean a 7-8 story building, most likely. The coverage is pretty small, and from what the dogstar maps show, the signal doesn't reach the BUR airport.

The North Hollywood/Burbank repeater is located at coordinates of 34.145556, -118.369722. The height of this repeater is 90 feet. Power is 800 watts EIRP. Orientation is 330 degrees with a beamwidth of +/- 40 degrees (from 290 degrees to 10 degrees, i.e. from about due west to about due north). Dogstar map shows that to reach to about the southern area near BUR.

There are also two fairly high-power LA repeater (13,800 watts, antenna aimed north +/- 32.5 degrees). That one shows coverage to all of Glendale and Burbank and significantly north of those areas.

So that should answer some of your questions. Try to go that site and see the coverages for yourself. They are impressive. The first one above gives you the location of one of the lower power repeaters.

One of the high power repeaters that covers that area appears to be at the end of Briar Summit Drive, what appears to be residential. It's hard to see from the satellite image, but I don't see a building there. Shows the antenna 50 feet above ground. I'm wondering if there's a short radio tower (like a two-way radio tower) there.
