We've been using the Triumph-3 and LS+ for a few months now. Previously we had been using the LS & Triumph-1M. While the new equipment outperforms the older models in many aspects we feel like the UHF radio performance is lacking. 2500' seems to be the max range for the T-3 on a 2 meter pole with the included external antenna (on both the T-3 and LS+). There's slide from July's workshop that illustrates what the RSSI value should be at the rover and ours is within tolerance, so I don't think anything is wrong there. We purchased the UHF Antenna, 5/8, 5dBd gain, NMO
& UHF Ant Cable TNC/NMO/Pole Mount, (12ft/3.6m) to use on the T-3 instead. At the same height it doesn't seem to be much of an improvement over the little one that came with it. If you add a few feet to it it helps, but it's not game-changing.
I was wondering if maybe we're doing something incorrectly. I wish I had the equipment in front of me to confirm everything, but I'll list what I think are the pertinent settings as best I can recollect. We got the 460-465MHz option for the aforementioned antenna. Screwed that onto the pole mount and attached it to the T-3 with a recommended adapter. The LS+/T-3 is set to use 462.something Mhz. I believe it's set to D8PSK, 1W, 12.5Khz, RTCM 3.2? (whichever one works with GPS, Glonass, Galileo, and Beidou, but nothing more - it's the option that says to use D8PSK when you go to select it). On the LS+ under UHF options it's set to use the external antenna. I don't know if there's an option to configure on the T-3, but I haven't been able to find it.
While on the subject of antennae I have another question. I was told not to have the UHF equipment on without an antenna connected or I could damage the equipment. Is this true for these devices? Does it matter if it's 1 watt? Could we switch between the little antenna and the big one on the LS+ on the fly? what about at the T-3? If not, is there a safe way to do this (maybe turn off UHF temporarily on the LS+? Also, say we're not using the LS+ for a half hour and want to just leave it on in the van. I feel like it's wasteful leaving it trying to do what it does while struggling so hard, is there an equivalent to "standby" or a toggle for satellite tracking?
And since I have the potential to have insightful people read this, one last question about the T-3. Granted I haven't done my due diligence by searching for the answer, but just quickly: is it possible to transmit connections from the T-3 to the LS+ over the internet using wifi at both ends? I know there's the option for a SIM card for both. Before we pursue that route we wanted to play around to see how effective this setup would be in some areas we work.
Thank you & happy friday.
