It's NAB time! And it's LIGHTNING season. If your going to NAB please stop by the Broadcasters General Store booth, N2421 to see the answer to coaxial lightning protection, the 1/4 wave tuned stub or 1/4 wave shorting stub. A 4 1/16 stub will be on display for your inspection. Thank you in advance for your consideration.

TWiRT 621 - 5 Things to Know About FM Transmitter Sites with Hal Kneller

Some technical advice is timeless. Other tech advice changes with the times. Such is the case with FM transmitter sites. Now more than ever we broadcast engineers need to apply the right safeguards and approaches at today’s FM transmitter sites. Situated under tall lightning “attractors” - otherwise known as “towers” - FM transmitter sites need a mix of time-tested design care and contemporary precautions. Hal Kneller is a 40+ year veteran of transmitter sites, and his Florida home provides plenty of experience with lightning protection, whether the equipment is old or new.

Spring is just around the corner which means Lightning is just around the corner. Prepare for lightning with a Xenirad 1/4 wave shorted stub. The Xenirad stub creates a full stop for lightning before it hits your transmitter. The stub does not cause any loss of signal and can be tuned to minimize minor VSWR in the system. Should you need to change frequencies the stub is frequency agile and can be retuned to your new frequency.
