fremont Posted May 29, 2022 Report Share Posted May 29, 2022 I wanted a monoband VHF antenna which I could use at hunting camp for both ham VHF frequencies as well as MURS. Decided on the Diamond M285. (I got the M285SNMO model as my mobile-to-base bracket is a Tram 1465 with a NMO-to-UHF mount.) This antenna is intended to be tuned and comes with a cut sheet. Originally, I wanted to cover starting at 144 MHz through the entire MURS band up through Blue/Green at 154.600, but I found I couldn't get there without wiping out too much of the ham band. (It's about a 7 MHz range to maintain less than 2.0 SWR.) I ended up cutting off 2" from the 47.25" antenna and ended with a midpoint (lowest SWR of 1.18) around 148.853. Used 20" radials on that Tram bracket. Eager to try it in the field. Quote Link to comment Share on other sites More sharing options...
