I use my omni x strictly for P25 800mhz trunking system in this article in RI. It sure does pick up the towers effectively more than enough. Probably much too well trigger I noticed the simulcast concerns are somewhat worse around the Providence zone in comparison to Once i use my 800mhz mag mount. Possibly the omni x staying up higher could possibly be having overloaded trigger the towers aren't significantly from listed here.
i didn't return from the thread to check out what freqs your general public security is on, but, assuming It is really from the 700-850 MHz variety, how is it executing buying those up? any more distant municipalities the outside antenna is selecting up, vs/ the original whip?
Ubbe stated: A dipole will work a lot better than a discone or an Omni-X at 800MHz. Attempt to set one up yet again, like a take a look at, and with coax that doesn't attenuate an excessive amount of on the lenght and frequency made use of.
Attackron stated: combined with the lmr400 periods coax im getting a fantastic 120 miles furthermore radius, no kidding you. sweet unf/vhf and 800mhz trucking that i just was not able to acquire with my diamond. Now i thoughts you This really is in my attic !!!!!
Thats a hard dilemma to answer. Perfectly the omni is particularly tuned on the bands it operates on, where by a discone is not really tuned to something unique. But discones experience at the time You begin going approximately 800mhz. The omni is tuned to 800mhz so a single would think it hears better than discone.
N6BY mentioned: Thats good. When you are like me you will need a person for TV and one particular for scanning on your own roof. I have acquired 450 and 900 MHz vertical Yagis set up over a rotor on my roof for scanning (In combination with a log periodic OTA antenna).
In any case I wish to consider that off roof and utilize it cell it's possible. So the only thing I seen in a different way With all the omni x was the PROVIDENCE method is just not as robust as it absolutely was using the mag mount. I believed It's possible the omni could possibly have a SLIGHT directionality to it. Probably the discone is just too near. All one other zones on P25 come in loud and crystal clear entire scale. I am gonna go out and TURN marginally the omni to view if which makes any variance.

Many thanks, that feels like it would be appealing to watch and decode. I just appeared it tgagrand up and its unencrypted FFSK modulation at 1200 baud. "SDRTrunk" incorporates a decoder for it below: DSheirer/sdrtrunk
That is great to below that it's Operating fantastic for you personally. I have Dave's VHF LP and is superb and very reliable.
"Antenna gained! Wonderful support and excellent quality solution! It is too chilly right here to become exterior installing antennas, so it's just leaning versus the wall within the corner of my Office environment, and nonetheless it nevertheless provides an extra couple of bars on signal energy. Amazing antenna."
"Merely a Notice of thanks; Omni X is up at 50 ft over the tower-operates good. Many thanks for the perform and a focus."
I'm wanting to know if I will be superior off that has a Discone and 900MHz antenna then make use of a diplexer, but if I could get it done with a person antenna that will be great. Simply click to grow...
Does any person determine what array of freqs the Omni-X covers. The Web page only says Multi-band extensive coverage and I'm curiuous what precisely that includes.
