| | | They grate on your nerves, those shrill squawks and squeaks, whistles and tones that sporadically erupt from even squelched marine vhf radios. Pure noise to most folks, "Intermod" and "Out-of-Band Interference" are what experts call it. And sorry to say, the closer you get to busy seaports, harbors or shipping channels, the more likely you are to experience this interference. To reduce the affects, Mariners have traditionally used externally mounted notch and band-pass filters. Unfortunately, these bulky filters are costly and require connecting cables that may decrease the sensitivity of your marine VHF system. But now, after more than two years of extensive research and field trials, Shakespeare engineers have developed a revolutionary filter technology that can dramatically reduce the annoying affects of Out-of-Band Interference in your VHF Radio. Best of all, the filter | | circuits are built right into the antenna. There are no power connections or special cables of any kind. So all you do is install the antenna as usual. And since these special filters have less than 0.25dB insertion loss, there is virtually no affect on your transmit range. Available only from Shakespeare, this revolutionary technology is offered in two new antennas; the 8', 6dB Galaxy 5225-FLT and the 17'6", 9dB Galaxy 5018-FLT. Both feature all the quality and performance you expect in a Galaxy antenna. Just pick the one that's right for you - and enjoy the quiet! • Greatly Reduces Pager and Intermod Interference • Patented - Special, High Efficiency Filter Built-In • Installs As Usual - No Special Cables or Power Required • Virtually No Affect on Transmit Range • Two Versions: 8' with 6dB Gain and 17'6" with 9dB Gain | | |
| | | Typical Marine VHF receiver responses comparing the new Eliminator Series and an ordinary antenna. Notice the dramatic reduction of annoying squelch breaks at the "Normal Squelch" level. The Ordinary antenna had 5, while the Eliminator Series had only 1. | | This chart displays the attenuation characteristics of the new Galaxy Eliminator Series Antennas. Notice the rapid roll-off of interference causing frequencies just below the marine band. By reducing "Out-of-Band" signals entering the receiver, not only are annoying squelch breaks controlled, but the Signal to Noise ratio on marine VHF channels is vastly improved for clearer sounding reception. | | |
