3G/4G Cell Sites Cause 7 GHz STL Interference
Engineers are now reporting interference to 7
GHz microwave receive sites, due to a recent FCC rule change. If your 7
GHz STL or ENG starts giving increased bit-rate errors and dropouts starting around
10 a.m., and doesn't clear up until after evening rush hour, you may consider
using one of our High Selectivity Filters or SuperFilter/LNA Systems to clean
up your 7 GHz STL or ENG Receive Site. Engineers report -50 dbm paths being
reduced to -98 dbm, due to desense in receiver front ends.
Call Lloyd at 954-850-1016 for details.

WE SPECIALIZE IN RELIABLE LONG RANGE DIGITAL MICROWAVE COMMUNICATIONS
Interference Proof ENG Filters, ENG Antennas, and Complete ENG Antenna Systems.
Our Filters, LNAs and Upgrades prevent Interference from Cell Sites, WiMax, and Satellite Radio Repeaters, etc to new and old ENG Receive Sites. *SuperFilter specs-click here*
We combine our Ultra Low Loss Frequency Agile Filters with our Ultra Low Noise Amplifiers to produce our custom made SuperFilter/LNA.
The ENG Filter and ENG Low Noise Amplifier in each of our SuperFilter/LNAs is custom designed to meet the RF rejection and gain requirements for each of your ENG Receive Sites. We eliminate AWS and PCS Interference that reduces range for other manufacturer's "state of the art" ENG Antenna Systems. click here
We condition the received signal BEFORE it hits your receiver, and strip away unseen interference that reduces range.
Our Single Channel ENG Filters and STL Filters eliminates adjacent channel interference by 100 db, for ultimate reliability and long range for COFDM, QPSK, QAM, and other Digital Modes.
You can lose your audience with one bad shot !

When GOODYEAR needed to do Live HD shots for the ESPN '07 HD Super Bowl Show, they trusted our filters to clean up their BLIMP's HD receiver.
Go Directly to Filters and LNA's for the 2 GHz Digital Band
The first Advanced Wireless Services (AWS) FCC Auction is completed. AWS-1 deployment begins February, 2007
Only our ENG & STL SuperFilter/LNA will filter out high power AWS / Cell Site signals, and withstand lightning hits that kill other ENG / STL Receive Sites. Call 1-954-850-1016 for details.
Advanced Wireless Service Band Plan
Only Phillips Micro technology allows you to receive the 2 GHz BAS Band without interference!
Eliminate AWS and PCS Interference:
Our ENG & STL SuperFilter/LNAs are compatible with the New Band Plans.
Get rid of Interference, and get more Range NOW.
A call is free, but a lost shot can be costly.

LOSING ENG RANGE? Interference? STL FADING?
ENG/STL receivers rely on external high-selectivity filtering ahead of the LNA to eliminate overload and desense from out of band Radar, PCS, XM-Radio, and other RF sources.
We are the oldest Corporation in the U.S. for eliminating these unwanted signals, and providing you with reliable long-range communications in today's crowded bands. In addition, our SAW filters will eliminate Adjacent Channel interference.
KABC-TV's Mt Wilson ENG Receive Site uses our SuperFilter/LNA 50' from a UHF HDTV Transmit Antenna
When KABC's ENG Site was blasted by the 3rd harmonic of a new HDTV Station only 50 feet away, we got a call at 2 pm. By 7:30 pm a completely new LNA system was on its way overnight to be installed the following day. It had 120 db attenuation at the offending frequency and PCS frequencies, but still allowed their helicopter to produce clean pictures, with its high sensitivity, and 50 db IP3 LNA.
WOR-TV used our SAW Filters in their ENG Receivers atop the World Trade Center until its demise on 9-11.
WGN-TV and Chicago's CLTV 24hr Cable News Channel both use our SuperFilter/LNA
As the noise floor increases, and the range on ENG (BAS) channels appears to decrease, with ENG channels becoming "noisy" or having horizontal flashes going through the video, and in some cases, having some channels totally unusable, many more stations with relatively new "state of the art' antenna systems are upgrading to our LIGHTNING PROOF SuperFilter/LNA.
When KSAT-TV wanted a lightning proof LNA, we sent them our SuperLNA. Now they get coverage from places they previously had no signal at all.
KTKA-TV uses our 38 db gain SuperFilter/LNA for 75 mile Live Shots.
We have Ultra Sensitive, Ultra Selective RF Antenna Systems & UPGRADES from 10 MHz to 40 GHz
We Custom Design each SuperFilter/LNA Systems to YOUR Individual needs, with custom selectivity and gain for high RF areas. Eliminate RF interference before it hits your equipment.
WSOC-TV, Charlotte North Carolina, has had 5 SuperFilter/LNAs in operation since 1996.
Charlotte N.C. was one of the first test cities for PCS.
WMAR-TV's ENG Receive Antenna is 12 Feet from a Rooftop PCS CELL SITE
WMAR-TV's ENG Receive Antenna looks directly into the main lobe of a rooftop PCS site 12 feet away, pumping out hundreds of watts per channel. Their new MILLENNIUM receiver would not work. They installed our SuperFilter, and can now cleanly receive 2 Ghz Band, including Channel 1. All interference is gone, and the noise floor is -94dbm!

In addition to our SuperFilter/LNA Systems, We also offer Surface Acoustical Wave ( SAW ) Filter Modules. When added to your Receiver, they provide an additional 60 db of Adjacent Channel Rejection. This allows you to use channels that are next to an STL or other ENG station shooting to the same receive site
