I suppose the shortest component that's the greater diameter tube for being for the higher freqs, with the massive diameter allowing for these types of a wide bandwidth, and another aspect pairs to get for the two VHF band sections. My antenna analyzer only goes approximately a hundred and seventy MHz. I might love to see your entire plot nearly one GHz.
how well does it pull in 2m/70cm repeaters vs. an HT w/ a whip? i failed to return throughout the thread to discover what freqs your public security is on, but, assuming It really is inside the seven hundred-850 MHz variety, how is it performing picking These up? anymore distant municipalities the surface antenna is picking up, vs/ the original whip?
A dipole will get the job done a lot better than a discone or an Omni-X at 800MHz. Try to set just one up once more, as a examination, and with coax that doesn't attenuate an excessive amount with the lenght and frequency utilized.
A handful of decades back I wrote an SDR plan - "DR Processor". It's got standard SDR features coupled with tone squelch, a large spectrum Screen mode, and primitive frequency scanning ability. It really is downloadable at n6by.com . It just demands an Extio DLL to your SDR.
I am wondering if I could well be far better off having a Discone and 900MHz antenna then make use of a diplexer, but when I could get it done with a single antenna that could be wonderful.
In summary, with two days in so far I am very pleased with the standard and efficiency from the OmniX. I was also happy with the sale transaction process and communication I obtained from Dave at DPD.
I have obtained the lesser Edition and it receives a lot of the UHF stations listed here inside our space with out any kind of pre-amp. I can just maintain it up in my front room and lock some in which have been sixty miles away on my TiVo. They are both of those very nice antennas for the worth!
” That’s why we’ve rounded up 10 legal, artist-pleasant platforms that hit all the appropriate notes — tgagrand no viruses, no copyright trouble, just pure sound bliss.
I can't get it up as higher as I'd prefer to due to HOA police, but it is a obvious enhancement from the handheld scanners rubber duck, that's for sure!
That is great to in this article that it is Functioning great for yourself. I have Dave's VHF LP and is superb and really strong.
Unbelievable outcomes! this point brought my SDRPlay and my whistler 1098 to lifestyle. In no way read rail website traffic listed here because the closest is thirty miles from below and finding up analog from 60 miles away. Also, getting directional, my regional palmetto P25 system has missing it'd simulcast troubles. Killer scanner log periodic antenna.
I haven't performed this in 4+ several years, but utilizing WIN500 software and Radio Reference it wasn't as well hard.
I monitor a P25 simulcast method in this article in RI. I have been Formerly employing a DPD 800 mhz mag mount up on roof. Reception was Terrific With all the mag mount. But the location I mounted it appropriate over a floor airplane which has a fat in it to maintain it in position, is not likely appropriate. See photograph. That metal plate is a computer side deal with bent into condition with a piece of 2x3 screwed into bottom so it stays place. To date even in the last wind storms it didnt go.
The Scantenna is suppose for being omnidirectional but when I had them mounted exterior I discovered it favored certain directions and lacked in Some others.
