From concept to completion your transmitter site is custom built to meet the needs of the station while keeping an eye on reliability and beauty. Multi-transmitter, multi-antenna facilities are designed and built to your specifications. Transmitter sites do not have to be ugly, they can be works of art that stand the test of time.

We Speak RF, fluently.  Using laboratory grade instruments from companies like Rohde-Schwarz, Copper Mountain Technologies, and Agilent, we can test, troubleshoot, repair and tune your equipment to get you back in proper working order.

Xenirad makes 1/4 wave shorting stubs.

The stubs provide a DC path to ground to protect your transmitter from lightning. They are frequency agile and can be retuned to a new frequency if the need arises.
