Here's a microprocessor-based system designed to monitor a tower's beacons, obstruction lamps, flash rate, photo control operation -- even the presence of an ATU heater bulb for winter months.
Dehydrators and nitrogen are the common gas sources, but are you absolutely sure of the line pressure and supply pressure?
Air-cooled FM transmitter
Emergency radio transmission
Hosted by Barix partner StreamGuys, the application serves as an online center to configure and monitor the audio transport bridge while providing a relay of the audio feed.
At the heart of the moment method proof is a computer model using an appropriate software package, however, the moment method proof, is not applicable in all cases or array designs.
Voltage sampling unit
FM band pass filters
Looking to add or upgrade IBOC? Here’s what you need to know.
With all the mysticism stripped away, science clearly explains the causes and functioning of lightning. Ron Nott reviews the current best practices to mitigate lightning damage.
LED lighting is a cost-effective approach to obstruction lighting.
The NAB Fastroad project funded the report, which includes a proposal for industry-standard energy efficiency rating for transmitters.
FM translator service, since its inception in the very early 1970s, has been subjected to several major technical overhauls.
Lighting surge protectors
Understanding the mechanics of your RF program delivery system, and maintaining a keen grasp of the associated fade margin can go a long way to diagnosing the rare, but ultimately problematic impact path failure can have.
The master antenna system mounted on the Empire State Building suffered a major lower bay failure on Oct. 18, 2010.
One good working definition of the Smith chart is that it is simply a graphical calculator for normalized impedance and associated RF parameters.
Fixed directional couplers
Satellite radio images on TV
Broadband motorized switch
8dB FM IBOC hybrid injector
MACXLine rigid transmission line
The bottom line is that without maintenance, transmission line will ultimately fail. The good news is that with regular and periodic inspections, the likelihood of unplanned failures is greatly reduced.
