Built from scratch to serve the Gila River Indian Community in Arizona
January 2015

The Gila River Indian Community through integrator Pacific Design & Integration (PDI) came to us asking for help with building a regional low power TV (LPTV) network from several FCC construction permits that had been approved.

First, we evaluated each CP by predicting signal coverage. We found that with a few modifications, we could build three stations that would cover the target 583 square mile community. We applied to the FCC for modifications to those three CPs to correct coverage.

While waiting for approval, we created a budget. PDI planned the master control systems while Signal Wiz planned the RF systems. We chose antennas, transmitters, supporting hardware, and a multiplexer to serve all three sites.

Upon approval of the CP modifications, we purchased the equipment and worked with Gila River Telecommunications tower contractors to install the antennas and feedlines. Then we installed and tested the transmitters as PDI finished master control. We were able to meet their 2014 year-end deadline, and GRBC began programming local content immediately.

Later, GRBC asked us to come back and install a ground-mounted satellite dish to receive the First Nations TV network.

We followed up with field strength measurements and training in choosing the right receive antennas for their community members.

We loved working with Bruce Holdridge of GRBC in Chandler, Arizona, as well as their staff, contractors, PDI and our vendors.

Signal Wiz can offer any, or all, of these services. We work with trusted partners to get your project completed on time and on budget. Check out our past experience portfolio. Give us a call at 858-349-9191 or send an email message to

A makeover and maintenance
Starting June 2012

Signal Wiz was originally called in to address a transmitter emergency. The problem turned out to be overheating that we fixed with some ductwork.

That began a relationship in which we made a series of small improvements to increase redundancy and improve quality in order to avoid downtime, both at the transmitter and studio. We set-up new racks and patchbays, and improved the EAS system. We installed a full-sized satellite dish for network service, and set-up a carrier-grade IP microwave system for a digital STL and control. As time passes, we've been needed less and less, and we're proud of that.

Signal Wiz can file applications, install equipment, maintain it, and train you. Give us a call or send an email message.
