The aluminium tubes that sits on the plastic tube are tuned to around 400Mhz and therefore are so huge in size that it Most likely handles 100 MHz vast frequency assortment. The X aspects are tuned for VHF-Air and VHF 150-170MHz.
i didn't return with the thread to see what freqs your public security is on, but, assuming It really is inside the 700-850 MHz range, how is it performing choosing People up? any more distant municipalities the outside antenna is buying up, vs/ the initial whip?
A dipole will perform much better than a discone or an Omni-X at 800MHz. Attempt to established a person up once again, to be a examination, and with coax that does not attenuate a lot of at the lenght and frequency utilized.
Attackron reported: coupled with the lmr400 instances coax im obtaining an excellent one hundred twenty miles plus radius, no kidding you. sweet unf/vhf and 800mhz trucking which i just was unable to acquire with my diamond. Now i intellect you this is in my attic !!!!!

I'd their log periodic which was an excellent performer, but my set up is far more conducive to omnidirectional antennas listed here, and so I sold it.
It's a pretty good antenna. Crafted similar tgagrand to a tank. Great reception. I had been up and down ladder seeking unique heights and going through it a number of distinct directions. I believed it's possible if I in fact lowered the antenna that might help considered one of my zones (P25 simulcast) are available a bit greater. Not a heck of quite a bit but right after a great deal of give and take I made a decision to set it back as much as it's authentic peak. I marked the mast with waterproof marker to receive it precise.
N5XZS stated: I obtained Sam Golf equipment and Walmart nearby be cannot figure out their freq, most probably in UHF band over anything.
Many thanks, that sounds like It might be appealing to watch and decode. I just appeared it up and its unencrypted FFSK modulation at 1200 baud. "SDRTrunk" contains a decoder for it in this article: DSheirer/sdrtrunk
That is great to listed here that it is Doing the job good for yourself. I have Dave's VHF LP and is excellent and very reliable.
Many thanks for that rationalization. I for one particular recognize your posts and discover them technically educational and not at all such as you're only seeking to promote goods, but alternatively tell and teach we individuals.

Glad to listen to the affirmation over the OmniX from DPD. No lower band up listed here whatsoever, so no worries there. Your image places mine to shame ;-)
The cable run is identical RG6 that came With all the Scantenna acquire when I had that installed about five a long time in the past. I used to be fairly satisfied with the general performance and did not want to take a position in owning that transformed out.
