MP Base antenna

[Ret_Batt_Chief]

Has anyone tried the MP Antenna-Super-M Ultra Base Antenna?
Started with Diamond discone. Read that Omni X was better, but UHF got worse.
I monitor mostly VHF-UHF analog. Some 700 digital trunk.
Looking for the absolute best multi-band outdoor antenna on a 40' mast.

Perhaps go back to the discone. Try an FM radio broadcast filter and a pre-amp (after filter) with no more than 10db gain. As for 700 MHz, unless the signal is strong into your discone, get a dedicated 700MHz antenna along with a diplexer so you can feed both antennas to your scanner. Hopefully you are using LMR-400 coaxial cable, or something with low loss.

You may have nearby RFI from other sources as well. I have a simulcast paging system on 152 MHz that is so bad, I use two filters just to block that signal itself.

I use a Larson tri-bander with a ground plane kit. Seems to do well on all bands. I'm picking up 7xx.xxx MHz at about 35 miles as the crow flies. No filters. 22 ft. AGL. 60 ft of LMR 400. I don't have any other strong signals near me. YMMV.

Do you mean this thing or the one with only three elements on the top and bottom?

Yes, that one

Yes, that one

I picked one up cheap on eBay years ago and it works about the same as a D130 or old Radio Shack Discone. And all those take a dive in gain at the horizon for 700/800MHz reception. They only thing it might do is slightly reduce deep fades from mobiles with multipath to your location due to the strange bent up radials. That is the claim of this antenna and with some testing I have noticed a little less deep fades where a moving mobile will not flutter into the noise as bad in the hilly area I'm in.

If you need good 700MHz reception and get one of these I would recommend supplementing it with a good 700/800 antenna and diplexer.
