Anyone heard of these antennas, a friend recommended one, but I had never seen one?

I have the 10-40 ground plane and it does really well. Tom has a great reputation for
his designs. I've talked to a couple over the air that had the stealth like you're looking at in HOA and loved them.
They're pricey but very well made and you get great support.
There's others out there, check around. If you do go with the ZeroFive you won't be disappointed. Just my .02

there was a thread about this a while back

This ought to be worth discussion.

a new thread is a good idea IMO .


i did notice the taller 15 meter version of the same antenna is only $239 compared to the 11 meter $399 one .
so cb'ers have tp pay $160 more for the shorter version . even the 35 ft 20 meter version is only $299 .

Anything can be made resonant, and any input impedance can be matched to the rest of the system to make an antenna usable. The key word in that is 'usable'. That does not mean it will work 'well', just that it will be usable. Shortening an antenna from a typical 1/4 wave length means that it's performance will also be 'shortened', when compared to a 1/4 wave length vertical antenna (same for a 1/2 wave, 5/8 wave, any particular 'size'). It's really as simple as that.
If that reduced performance is 'good enough' for you then have at it. But don't think that it's the 'best' there is by any means. It can certainly be the 'best' that you can expect/get considering your particular mounting/living circumstances, but that's completely different than 'best there is'.
As for the prices? I don't think you want to know what I think about them...

Any vertical without ground radials is only half an antenna.

I have tried the Cushcraft R7, it worked, but so did my 1/4 wl 40 meter vert with ground radials, the 1/4 wl with ground radials hands down much better than the cushcraft.

If you can get a 32' flag pole up, (chain link fence posts comes to mind here, cheap and easy to work with from the home supply stores, or electrical emt conduit).

Bury some ground radials, 16 or 24 of them. bury them in the grass, I used 24 gauge green insulated solid copper wire, (had a 5000' roll of it).

It works great on 40 and has out performed the other commercial made verticals on the other bands.

If you are going to just use 100 watts then a automatic tuner at the input, in an environmental sealed enclosure or some tuners are even designed for exposure to weather marine type automatic tuners.

a unun at the feed point and put the rest of the money you save in your pocket compared to the zero five price.

Default Zerofive Antennas

Most of the ZEROFIVE ANTENNAS are non resonant vertical antenna that work well for DX, first of all being non resonant they don't bring in extraneous band noise, you get a lot better signal to noise radio in less than ideal radio conditions, (you can hear the other stations better) Thats better than trying to take noise away from the signal with a DSP unit that always adds something to the incoming signal, fact is a signal will always come over the noise in radio reception, an antenna tuner will have to be used for a decent signal output of the radio used. I have a ZEROFIVE 43' that I have been using for 3 years in two different configurations with good results on 10-160m. My first setup was the way ZEROFIVE recommends installing the 43 vertical using a full range tuner and using a UNUN and a coil on the 43' vertical antenna this worked well up to 200 watts at my location, but after 200 watts the efficiency dropped. the present setup uses a screwdriver antenna in series with the 43' stinger and 3500' of radiales that range from 18-60' under the antenna, the antenna system will take 1000+ watts with 1.1 SWR which works very well on 160, 80 and 40m with fair results on the upper bands.
By taking off 5 section of the vertical stinger and making the stinger 27' that made the antenna a flame thrower on 40m it still works 80 an 160m. I just ordered the 27' Zerofive ground plane antenna that works 10-40 with an antenna tuner, for the higher bands to take advantage of the higher Sun Spot count for some good DX..........KB6HRT

i thought a resonate antenna was best . i also thought DX/skip performance was a terrible way to judge a antennas performance since it's all about conditions .

thanks for correcting the bad information i picked up along the way .
