I suppose the shortest component which can be the much larger diameter tube being for the higher freqs, with the massive diameter enabling these a broad bandwidth, and the other element pairs to generally be for the two VHF band sections. My antenna analyzer only goes as much as 170 MHz. I'd like to see the whole plot nearly one GHz.
550 MHZ is just my imagination! And by the way. Been employing a ST-2 plus a DPD productions Omni x For a long time which is just as excellent. Also reading through comprehension would support you numerous. Reread my post and see it absolutely was just a experiment.
I used it briefly lead to it absolutely was however winter and way too cold to perform much outside antenna operate. After i did have the LMR400 Soon after it designed a huge variation. I am checking a P25 procedure in this article in RI. 800mhz. I also have the Newport Naval base on 380mhz and also the omni picks up the signal one hundred%. Newport is slightly below 1 hour far from me with a big hill in the way. The omni doesnt do lowband.
Several decades ago I wrote an SDR software - "DR Processor". It's fundamental SDR operation along with tone squelch, a broad spectrum Screen mode, and primitive frequency scanning ability. It's downloadable at n6by.com . It just desires an Extio DLL for your personal SDR.
By no means read rail targeted visitors listed here because the closest is 30 miles from in this article and finding up analog from 60 miles absent. Also, remaining directional, my nearby palmetto P25 technique has dropped it'd simulcast issues. Killer scanner log periodic antenna. Click on to develop...
Price ranges look like superior when compared to Other people, but this is actually a illustration of receiving That which you paid out for. Shipping and delivery is rapidly! Dave is extremely attentive to email messages, even several years once the sale.
I Individually would love to maintain producing unique consumer stage stuff that many other corporations don't want to hassle with. I'm engaged on making our possess anechoic chamber for screening, and I've also been engaged on some other new things, like an SBS-1 design. But the long run depends on regardless of whether the consumer industry is viable plenty of to assistance this.
If it works much better you may make use of a diplexer to possess the Omni-X go as many as 500MHz then the diplexer will make use of the dipole for something above 600MHz.
Convey to us about your coax type, coax length and any adapters maybe you have inline way too please as I presumed it is actually deployed with a mast. If you need to give us extra readings, it will be appreciated.
JoshuaHufford said: That's the purpose I am questioning regarding the Omni-X, curious if it does better than a discone at 890-960MHz.
South Alabama, Gulf Coast Feb ten, 2008 #one Just so notes for anybody in the market for an antenna which was produced only for scanners, not a ham. the DPD OmniX Multi Band Scanner Antenna is simply fantastic. I mounted it in my attic and it just blows my diamond d-130j slap out the h2o, arms down the greater antenna.
"Simply a note of thanks; Omni X is up at fifty feet within the tower-will work fantastic. Thanks on your operate and attention."
Acquired the antenna and mast and was on just how out to install it to the playhouse roof. The only thing that stopped me was the thunder and lightning. I know about the inverse rule of Placing up an antenna in adverse temperature, but I attract the road at lightning while Keeping a metallic rod!
The cable operate is similar RG6 that came Along with the Scantenna buy when I experienced that mounted about five yrs ago. I was relatively happy with the tgagrand functionality and didn't want to take a position in getting that transformed out.
