Designs that employ parallel tuning require an amplifier to couple the resultant high antenna impedance to the feed line, while those that employ series tuning can be passively matched to the feedline and have exceptional noise figure (NF) and intermodulation distortion (IMD) performance. Both forms of loop antennas require some form of tuning in order to accomodate the high inductive reactance of the terminal impedance. Small loop antennas have this characteristic, and small shielded loop antennas provide a good degree of immunity from low frequency electric field noise, which is highly desireable in urban environments. Physically small antennas that have a directional radiation pattern can be very useful when nulling out interference is desired. SWLs and radio amateurs living in confined areas such as apartments or in communities having antenna restrictions find small antennas and especially active antennas to be a practical solution. Box Tempe, AZ Senior Member IEEE Revised 7 March 2011 Trask, Active Short Dipole Antenna 1 7 March 2011 2 Introduction Active antennas are of interest to a wide range of users, from shortwave listeners (SWLs) and radio amateurs to designers of aircraft radios. An Active Dipole Antenna.ġ An Active Short Dipole Antenna with Remote Tuning by Chris Trask / N7ZWY Sonoran Radio Research P.O. Available active dipole antennas was the Datong AD270 and AD370, the former in-tended for indoor useage and the latter for out. Leeds manufacturer in GB, Model types from Great Britain, 10 radios, 22 pictures, 28 schematics, tubes, radio technology. In other words, a lot of US equipment has capabilities that might not be regularly used by US forces.Datong Electronics, Ltd. Also, these radios use different hop techniques in the HF and VHF ranges. I was under the impression that radios like the PRC-138 and PRC-150 (and similar radios) had hop for two primary reasons, to maintain interoperability with friendly forces with such capability and to maintain interoperability with SINCGARS radios that operate in the overlapping bands, primarily 30 to 87.875 MHz. I freely admit my search was not exhaustive, but most companies that sell hardware to the US mil do tout that on a product description.
I did a quick search, and cannot find that US mil forces have adopted either the HF-90M or the TRC3600. Should make it possible to ID either system when found on the air. Notice the HF-90M is 5 hops / sec and the TRC3600 is 10 hops / sec in voice mode and 20 hops / sec in data mode. Harris tactical VHF handheld, manpack and airborne radios are built on battle-tested Falcon. I was giving my radio room a clean out and found a Datong active antenna that I bought years ago and had forgotten about. Datong AD 370 outdoor active antenna.Covers 0,2.

Re: RF-5022 R/T E Operators / Programming / Install Manual Needed. Welcome to the Harris Radio User Group Anything Harris Alpha 2000 ( UHF / VHF). Also, good finds on the pdfs you have there.
As far as I know the most common frequency hopping capable radio systems that the US mil uses are HAVE QUICK and SINGARS.Īnd these are VHF and UHF, but not HF. Nick, my guess would be most likely military, but not US military. Mike, I would guess US military but it could be just about anyone with the cash to afford the equipment.
