kidphc Posted June 2, 2020 Report Share Posted June 2, 2020 I had done some SWR readings for a mag mount Nagoya UT72, Btech/Baofeng recommends for the GMRS radios. They do suggest using a proper NMO mount and another antenna. I am installing an Yaesu FTM400XDR and had picked up a Larsen/Pulse 2/70SH for use with that radio. So why not do a small review. I will continue adding to this review as I get more info. I will be getting the Larsen 2/70b in the future. Larsen Pulse 2/70 SH (link goes to dx engineering. Why, because Larsen's page is a bit of garbage) Vital stats:Mobile Antenna BandFrequency Coverage RangeVertical Antenna GainElement Phasing (wavelength)2 meters144-148 MHz2.1 dBi1/270 centimeters440-450 MHz4.0 dBi3/4 Larsen NMO mount Nothing special. Standard 3/4 drill through NMO. It was between this and the Laird NMO. Comes with 17 Feet of RG58. You will need to have a PL259 connector or N type fitting, with appropriate splicing gear. Here is a visual representation of the Larsen 2/70SH 1/4 NMO next to the Nagoya UT72 mag antenna. Notice how the Larsen (front) is a bit shorter looking. It is because of the way the NMO mounts versus the magnetic mount. It should be noted that a big CON of the Nagoya UT72 is you can not simply swap out the antenna on it. The connection of the base the location of the loading coil all cause it to be a real pain to find something else. If you go with a magnetic mount make sure it is an NMO style magnetic mount, so you can swap antennas out. Keep in mind the Nagoya UT72 is about $26 where a decent magnetic NMO without antenna is usally twice that price. Quote Link to comment Share on other sites More sharing options...
