Hello! I have several old MON-Series mobile antennas (MONR33, MON-52 and MON-53). The instruction manuals that comes with them all show a #K-722 base coil. There are no specs for this coil, and there are no markings on any of the coils I have (except for the Antenna Specialists logo), but The Antenna Farm carries them
, and their site shows them as:
“406-470MHz replacement coil for ASP7650 MOSAIC series antennas”
Under “MHz” it shows “406-470MHz”
I ALSO have an old A/S MON-58, which is basically the MON-52 whip with a base kit. HOWEVER, the instruction manual with the MON-58 shows a #K-222 coil, and the manual says “Marked 406-494MHz”, and the actual coil does have “406-494MHz” embossed in the top section of the plastic housing.
The upper whips for the MON-52 and the MON-58 are BOTH listed as #19-4645-1 in their respective manuals.
The MON-52 and the MON-58 are both rated for 25-1000MHz.
Now, here is my question:
antennas are rated for 25-1000MHz, and both
antennas have the same exact main whip, then why would they have different
