Hello friends,
I am having a heck of a time getting any range with my setup. Ya'll help me out here.
T2, LS, HPT435BT pushing 35watts w/ 14ft pole,
UHF Whip Antenna 5/8, 5dB, NMO
RTCM 3.0 Min, 0.2 Sec, 464.5 MHz (FCC approved),
D16QAM, 12.5 KHz bandwidth
I notice the quickstart guide states "Field test have found that D16QAM modulation decreases the working range of the radio approximately 20% as compared to DQPSK modulation." I'm guessing my radio don't have DQPSK, since I don't see the option?
I also notice the whip antenna manual shows cutting it? Right now it's already too short between the phasing coil and base per the chart? By about 1/4". Will this be a game changer???
Also, see my attached pic of a recent job where I couldn't get over 1 mile with this setup. Granted, I don't always spend the time to get to the highest point with my base, but not even a mile??? Come on. At my old place of employment, our old topcon hiper-v never required an external radio and worked all day in the same stuff at farther distances. Ironically, we did the south line of this same tract where I couldn't make it half way without losing radio.
This is the only thing I have really not liked about my system. I am going to try the Verizon jetpack, but no signal in a lot of places. What can I do to improve my radio range?
Green I was able to get it, RED was a no go at all. The 2 southeasterly ones were BARELY done. I know I'm not the only JAVAD guy in hilly terrain like this...
Thanks in advance.
