AR Modular RF is the leading supplier of booster amplifiers for military tactical radios. As such, the company gets lots of questions about just how much improvement can be expected when a booster amplifier is used.

Chris Heavens, Vice President/General Manager of AR Modular RF has authored an article to answer these questions, and to explain the many factors that affect the quality and distance of two-way radio signals. The article offers an honest assessment of how a booster amplifier can affect transmission/reception quality and distance of signals. Included in the article are results of real-world testing along with tips for improving signal quality when using a portable tactical radio.

The article, entitled "Communications Amplifiers" Can They Really Take You Farther and Help You Be Heard Better," is available for free download at AR Modular RF's web site and on the RF Globalnet and Globalspec web sites.

Just what is "better" needs defining of course; but simplistically you can either "go farther" or "be heard better," sometimes both at once, all other things being equal. The question of just how much "better" is a lot harder to quantify. ]]> Tue, 29 Jun 2010 12:58:35 EST http://www.arww-modularrf.com/PDFs/articles/PropagationArticleJune2010.pdf modularrfsales@ar-worldwide.com (AR Modular RF) http://www.arww-modularrf.com/pr/100318-250-Watt-Microwave-System.asp
The Model KAS2010M12 is a 19-inch rack-mount unit that features overdrive protection, infinite mismatch tolerance/VSWR protection, and over-temperature protection.

Included in the the KAS2010M12 is the KMS2010 module. The KMS2010 is also available separately. It provides up to 150 watts of power over the 1.75 to 1.85 GHz frequency range. ]]> Mon, 22 Mar 2010 07:52:02 EST http://www.arww-modularrf.com/pr/100318-250-Watt-Microwave-System.asp modularrfsales@ar-worldwide.com (AR Modular RF) http://www.arww-modularrf.com/pr/100204_ar-75_tactical_booster_amplifier.asp Thu, 04 Feb 2010 09:50:19 EST http://www.arww-modularrf.com/pr/100204_ar-75_tactical_booster_amplifier.asp modularrfsales@ar-worldwide.com (AR Modular RF) http://arww-modularrf.com/pr/090113_portable_booster_amplifier.asp AR Modular RF has introduced a new portable, lightweight, fully automatic band-switching RF booster amplifier for single or multi-band VHF/UHF tactical radio equipment. The new Model KMW1035 is a 50-watt amplifier that covers the 30 - 512 MHz frequency band using six high-speed auto switching filters to assure harmonic suppression.

1 The unit is SINCGARS, HAVEQUICK, and ECCM compatible. It includes voltage spike suppression, RF sensing, T/R switching, automatic level control (ALC), six automatically switched harmonic filter bands, and protection against antenna mismatch, over-temperature and accidental polarity reversal.

The KMW1035 amplifier is the latest member of AR Modular RF's line of rugged, dependable, battle-tested military booster amplifiers. ]]> Fri, 30 Jan 2009 09:12:00 EST http://arww-modularrf.com/pr/090113_portable_booster_amplifier.asp modularrfsales@ar-worldwide.com (AR Modular RF) http://arww-modularrf.com/pr/080710_booster_amplifiers_GSA.asp AR Modular RF has announced the award of a five-year General Services Administration (GSA) contract to supply booster amplifiers for use with tactical military radios.

The KMW1031 is the latest and improved version of it's popular 20W man-pack tactical radio booster amplifier. This new fully automatic version is smaller, uses the latest state of the art amplification devices such that it can be powered from one UBI-2590 or similar battery, and can be used in both 12 and 24 VDC vehicles. Like its predecessor the KMW1031 is fully submersible, with fully automatic band switching offering a minimum output of 20 watts across the full band of 30 - 512 MHz. It has automatic high speed switching of its internal filters to allow SINCGARS and other hopping modes across the full spectrum. Like both previous models it includes vehicle voltage suppression circuits, RF sensing Tx/Rx switching, and has an Automatic Leveling Control (ALC) that handles inputs from 1 to 10 Watts.
