Do you remember MEOV?
MEOV offered a wonderful means of providing a way around a potential difficulty in meeting the approved radiation pattern.
Kintronic Labs Kinstar
The first field-installed Kinstar antenna system is in use at KCST-AM, Florence, OR.
Station Upgrade: KEXS
It's not uncommon to find elevated tower bases, but to see a transmitter building sitting on 9' stilts is rather unusual. See why KEXS chose to not only raise the roof but also raise the entire building.
Dielectric, Exir Broadcasting and Telecom Create Sales Partnership
The agreement expands Dielectic's product line and allows Exir to sell Dielectric products.
Transmission lines
A transmission line is a far more complex piece of equipment than many people realize. In its simplest form it may be considered as just a pair of wires merely carrying ac power.
FCC adopts new methodology for AM proofs
At long last, the FCC is permitting directional AM stations and permittees to submit proofs of performance using moment modeling in lieu of proofs based on extensive field measurements.
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.
Connecting studio facilities and transmitters
32 Avenue of the Americas is home to one of several large Carrier Hotels in New York City, and as such was an advantageous location for our endeavor.
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.
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.
The path to upgrading
From finding land to filing a Form 302: an overview of the steps for completing an upgrade.
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.
Planning for a digital future
In 2005 American Tower was approached by current and prospective tenants to consider modifying the aging antenna and its combiners to transmit HD Radio. The result of this project is an antenna installation with greater capacity, additional redundancy, and natural transition path for the stations to go digital.
The road to antenna maintenance
Before any useful maintenance can be performed it is essential to know how a system is supposed to operate and also know the licensed operating parameters. A copy of the latest proof of performance and the current license are a good place to start.
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.
The final Element
Examine some ideas and items to look for in the budgeting and planning process as they apply to FM and AM antennas.
Applied Technology: Dielectric HDR Plus
The most daunting task of IBOC has been how to combine the analog and digital signals in a cost-effective manner. Dielectric believes it has the answer.
FM IBOC site preparation
What steps should you take when constructing a new facility for IBOC?
Site security
Although no amount of security can deter a determined intruder, a burglar will definitely look for an easier target rather than risk being slowed down by a facility’s defenses and be caught in the act.
Antenna currents and field strength
Sometimes we lose sight of the relationship between current in an antenna and the resulting field strength value.
Safety first
It may seem that a typical broadcast facility doesn't have all the safety concerns of a construction site or a manufacturing facility, but accidents happen.
