GeoBroadcast Solutions Names Jampro Antennas as Exclusive Supplier for MaxxCasting, ZoneCasting Networks
Jampro's antenna directivity supports the goal of GBS to provide maximized and targeted signal delivery across single-frequency FM radio transmission networks.
Antenna Installation
A pigtail jumper eliminates the potential problem of connecting a transmission line to an antenna.

Reception Issues Resolved
Need to pick up multiple FM signal from different directions? Here are some methods that will capture weak signals.
WAOK-AM Uses Method of Moments Proof
The FCC has allowed stations to use Method of Moments proofs, and WAOK-AM in Atlanta, is one of the first stations to implement the technology.
Method of Moments Modeling
In February 2009 the FCC formally permitted the use of Method of Moments (MoM) modeling. Kevin McNamara explains the concepts of using this tool.
Understanding Tee Networks
The tee network seems almost magical as it has the ability to transform between almost any two complex impedances using only reactive elements.
Directional Antenna Basics
Jeremy Ruck reviews the basics of directional antenna arrays.
SPX Communication Technology Dielectric DCR-XL
Low-power antenna
Method of Moment Proofs
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.

The Phasor
The upcoming generation of radio engineers will encounter a new ease of measurement as a fact of the Commission's new directional antenna proof rules.
Using the operating impedance bridge
The development of the operating impedance bridge by Delta Electronics about 40 years ago made antenna impedance measurements not only much easier to perform, but more accurate.
Thoughts about NEC 4-1
As time passed and DA design work received increasing attention, it became obvious that more information was needed about how the antenna worked in its environment once constructed.
First MoM AM Applications Granted
WKOX and WRCA are among the first stations to be licensed under the new rules.
