EMR Corp RF Preselectors vary from single or dual cavity resonator combinations, to mult-stage inductive, aperature coupled, or combline filters. Special preselector assemblies may include one or more of these devices in combination, multiple pass and stop band characteristics, and special notch elements according to the complexity of site requrements. EMR preselectors are designed to optimize loss, selectivity, and costs; with respect to the particular site requirements and frequencies.

Super-charge your reception by feeding your scanner with a wideband and/or multiple band-specific gain antennas!
This Co-Phasing Antenna Package is custom built by an Extra Class Ham Operator in the Providence area.
The purpose of co-phasing receiving antennas is to add receiving strength in directions that you may have weak, distorted reception using just a single discone or other type of wideband scanner antenna by allowing you to add multiple antennas to your mast and feeding them with a single coax line.
