Antennas
Vertical Radiators
Sometimes we tend to forget some of the fundamental facts of electronic life involving radiation which, after all, are requisite for radio transmission.
The Other Antenna
It's worthwhile upon occasion to look at more common technologies to see what the most up-to-date products are and how they relate to common applications. This article is about antennas we don't commonly think of for broadcast transmission.
Tweaking the antenna system
The last link in the broadcast chain under the control of the broadcast engineer is the transmitter and antenna system. From then on quality of reception is left in the hands of the listeners. Thus it puts the onus of transmitting the best possible signal on the station engineer.
Tennessee Turnaround
WKNO-FM, an NPR member station in Memphis, began operations on April 1, 1972, on 91.1MHz with 40kW of effective radiated power. The station launched its HD Radio signal in the fall of 2007. Up to that point, we underwent incremental upgrades and adjustments to the original installation.
The path to upgrading
From finding land to filing a Form 302: an overview of the steps for completing an upgrade.
A Foundation for the Future
In its most basic description, this project entailed the addition of a 40 feet by 60 feet space attached to an older, steel-framed transmission facility, but the story extends far beyond the basics.
Living with your license
Your new or latest station license has arrived. How you deal with it can have a huge effect on your future.
Jampro JHPC
Accumulated ice can wreak havoc on some antennas if you aren't careful. One station in Manistique, MI, has found the Jampro JHPC to be a reliable choice through the sever winters.
The vertical challenge
As broadcasters rush to prepare for adoption of the new standard, the time is ripe to step back to consider the state of the radio tower industry and the effect Revision G will have on it.
In tune with detuning
As cellular towers began to proliferate, the interference to broadcast antenna systems became apparent, and AM broadcasters sought redress from the FCC.
