Hi, my first post here. Passed my Technician's Exam a week ago and waiting for my call sign....
A few months back (before it occurred to me to get my Amateur License) I paid for my GMRS license and put up a Tram 1486 UHF Land Mobile Base Antenna up on 20' of 1.25" conduit. I cut-tuned it to a VSWR of 1.1 on the high-power part of the band at 467 MHz with a VSWR of 1.4 at 462 MHz.
The meter is a Surecom SW-102 Digital VHF UHF 125-525Mhz Power & SWR Meter.
My friend came by today with his dual band mobile and we found that the VSWR is 1.99 at 449.750 MHz and 2.29 at 445.925 MHz which seems to make good sense and is not great but workable.
What came is a big surprise was that on 2m at 144.310 MHz the VSWR reads 1.4 and at 147.580 1.12! How can this be? Will it be safe to transmit on 2m using this UHF antenna?
Thanks in advance.
