Castles wireless is point-to-point which means that to have service we must have clear line-of-sight from your location to one of the towers. We have 4 primary towers and a number of repeater/relay stations to service your location.

Capay Valley, Esparto & Yolo County

We can service any point up to 25 miles from Berryessa Peak that has good line-of-sight. That includes Woodland. If you can see our tower on top of Berryessa Peak then you most likely can get our service.

Solano, Yolo and Napa Counties

We broadcast 360 degrees from the top of Mt. Vaca and the tallest hill west and behind the Vacaville Prison.

You can do a preliminary site check for availability by putting in your street address and city.
Site Check Disclaimer - the use of this wireless site survey tool provides a preliminary site check only. Service is not guaranteed. A free site survey is available to determine actual line of site, distance, trees, obstructions, etc.

Castles technicians are always happy to complete a free sight survey.
Simply complete the Site Survey Form and we'll do the rest.

You don't even have to be home.

Don't have line-of sight?

If you don't have line-of-sight at your location, perhaps your neighbor does. If you have a minimum of eight (8) separate locations that have line-of-sight to another house or business, we can install a relay. One house or business must have good line-of-sight to the tower. We can complete a standard installation at that location and install a small pole-type relay that will relay the signal to the other locations. The location that hosts the relay must agree to provide 110V electrical and in turn receives Internet access at a significantly reduced rate.
