Tom, This one beats all verticals I have ever tried .

Time owned: 0 to 3 months

Was easy and fast to put togeather. I was only able to get down 3 radial before this latest snow storm hit but it is a killer on 40 20 and good on 80. Im'sure 80 will get even better as I get down those radials. Best built vertical I have ever owned. 73s Jack w8cfs

This 43" vertical is the best antenna I have ever used for 40 and 80.
Have used full sized Delta loop for 80m before and a Butternut for 80/40. No comparison.
Model this antenna all you want....it works great.
I am using it only for 80/40.
Also Tom is a pleasure to buy from.
Quick email respons and quick shipping.
A N D it is built like no other vertical.

Try it as a loop
|
Time owned: more than 12 months

This is an update to my review of this antenna on 10/24/08.
As stated previously, I have been using this antenna with a SGC 237 auto tuner, using a chain link fence as a ground plane. The antenna is mounted on a water pipe about 4 feet above ground. I suspect that the performance of this antenna would be improved with a good radial system in the ground instead of the chain link fence. I also suspect that the fence is making my signal directional. However, because the antenna is mounted on the edge of my lot I am unable to lay a good radial field 360 degrees around the antenna.
I recently tried an experiment. I connected #18 stranded insulated wire to the tip of the antenna. I then ran the wire over to a roof mounted antenna mast on my garage, and then back down to the base and connected it to the SGC237. The point where the wire connects to the garage mast is about the mid point of the 43 foot vertical.
So I turned the antenna into a large delta loop. Performance seems to be much better, especially on 17 meters up and also 160 meters. SWR is still flat on all bands.
I connected the wire to the tip using a small hose clamp. I did not want the wire on the ground side to get caught on anyone, so I secured it about 6 feet up the antenna with a piece of rope and then ran it along side the main element down to the tuner.
I originally tried #12 solid copper wire, but I found this bowed the tip of the antenna out too much. It still bows out with #18 stranded but not nearly as much.
You may be thinking, why not just hang wire in the tree and not bother using the zero five to start with. I would reply by saying the zero five in a loop configuration is completely in the clear – if you used a tree or tower for a support that would not be the case.

Have the Zerofive 43 foot multi-band vertical fed with a UnUn at the base and a MFJ Intellituner in the shack.
Used mostly on 80, 40 and 30 meters. I have a Force 12 beam for the upper bands. The antenna is mounted in a poor location, 10 feet from my house on the north and 10 feet from neighbors house on the south.
Pretty good shot to the east and west though.
I have only about 20 radials with the longest about 40 feet. Considering the location, I am satisfied with it's performance. I use it a lot on the 3905 Century Club Nets. Won't tune on 160 meters with the 4-1 UnUn but did tune on 160 meters when I was running the 4-1 Balun. Switched to the UnUn transformer as it seemed to improve my performance on 80- 30 meters. Won't tune with the built in tuner on my Icom 746 (non pro) when using the UnUn but would when I used the balun.
Construction is easy and simple. No traps or adjustments to make. It is very well made and un guyed. Excellent customer service from Tom also!

EXTEMELY HAPPY

I BOUGHT THE 10 METER SUPER GAINER FOR ZERO FIVE. I DONT THINK THEY MAKE IT ANYMORE. DON'T UNDERSTAND WHY, IT WORKS GREAT. IT IS A DX BUSTER. NEXT I BOUGHT THE ZERO FIVE 33 FT 10 TO 80 METER VERTICLE. IT WORKS SUPER. I MODIFIED MINE TO 43 FT. I WORK 10 TO 160. I TALKED TO A FEW STATIONS ON 160 AND WITH ONLY 100 WATTS GOT S-7 S-8 REPORTS. THEY WERE IMPRESSED I WAS ON A VERTICLE. MUCH LESS AT 100 WATTS. TWO DAYS AGO I HAD A FRIEND OVER AND I TALKED TO EUROPE AFRICA AND MADAGASCAR USING 100 WATTS ON 17 METERS. I USE MINE WITH A PALSTAR AUTO 1500 TUNER. I HAVE HAD SEVERAL VERTICLES AND NONE OUT DID THE ZERO FIVE. ONE CAME CLOSE BUT NONE EQUALED IT OR SURPASSED IT. 43 FT WITH NO GUY WIRES. GREAT ANTENNA, GET ONE YOU WON'T BE SORRY. GOD BLESS AND HAPPY DXING

Break through pileups
|
Time owned: 3 to 6 months
|
|
I have had the Zero-Five 43 foot vertical since April. My installation includes 56 43 foot ground radials with four other wires running from each corner of the radial plate to my chain link fence. I have the Array Solutions CG-3000 remote tuner (my LDG 200 Pro in the shack could not tune this antenna on all the bands). With this I can tune from 80 M to 6 M but I cannot tune 160 M. I am using Array Solutions’ Bias-T system to send the 12 volts to the tuner through the LMR 400 coax along with their antenna disconnect that isolates the antenna from the tuner when there is no voltage in the coax. I run only 100 watts. I took this long to report my results because during May and June I had some phenomenal power line QRN which wiped out most of 20 M. Prior to that problem, and now that it’s fixed, I can say that I have been doing great. With voice or CW (my main mode) I have been able to QSO with anyone that I can hear anywhere in the world. I can easily break through pileups with 1-4 tries. I thought that perhaps my advantage over other HAMs is that I am in the northeast. So I tried an experiment. I would listen to a good pileup until I heard a few HAMs in the northeast who, according to the QRZ site, were running full legal with beams. Then I would drop my call in and within 1-3 tries I got through. I would then move on to the next pile up while the full legal beam users were still trying to break the pileup. The customer support from Zero-Five and Array Solutions is great.

It's pretty much a bust under 20 or 40 meters
|
Time owned: 6 to 12 months

I bought and built the 0-5 43' all band vertical a couple of years ago, and finished the construction last fall. It's NOT an antenna that impresses me!
You can see all the details of my construction at www.n3eaq.net ... It's fine on 20 meters, It blows everywhere below, compared to my Alpha-Delta DX-LB+, and my 160m V-Beam is even better!
I can only guess that all the RAVE comments come from folks who have limited space, or have never used another HF antenna!
It has been cunstructed at my QTH at WELL better than most folk's specs, and Still, nothing that makes me excited!
I use it on 20m and up, and it works fine there, but was NOT worth all the $$$ and time I put into it!

Log Book Say's It All
|
Time owned: more than 12 months

I have had the Zero-Five for over two years and have used numerous rigs with this antenna. I have had no problems working 90% of the stations I hear. I work both SSB and digital modes and have worked lots of DX with 100w, I don't run an amp. I have a minimal radial system. According to all the info about radials the antenna should not radiate, but it does.
The Zero- Five works for me and my log book proves it. That is all the proof I need.

A 40m Vertical
|
Time owned: more than 12 months
|
All these 5's.., and I have to be the descending voice... I've had it for 2 years and my conclusion is, that it is an outstanding 40m vertical. It can be made to work any other band but the reception is disappointing. Case and point: shed mounted cushcraft R-5 vertical 40 feet away outperforms the zero-five on 20,17,15,10. Curiously, the R-5 is even on par with it and sometimes better on 80M(Receive) although the R5 wont transmit on 80. I was told by Tom that adding more ground radials would make no difference in receive, just transmit. I have about 10 radials..planned to add more. I also bypassed the matching balun to see if that was a culprit and it wasn't. All connections good, measuring 43 feet exactly, and connections with light ox-guard as stated in assembly directions. For 80 and 160m, a longwire at only 12 feet off the ground run through some trees gives better reception on those bands. For the good news: I have received excellent TX signal reports on 80m and the swr is pretty decent across the bands easily handled with FT1000 internal tuner. Sometimes stations that I hear in the noisefloor on 80 can hear me fine, and I've never had that situation until this antenna. As for 20M, the signal reports are usually-- say 90 percent better with the R-5 and occasionally slightly better with the zero-five depending on conditions. Perhaps more radials will solve that -- but keep in mind my major gripe is the low receive, and not such a great S/N ratio... and a million more radials wont address that, unless I'm misinformed. As for 10 meters, its no contest. The R-5 wins both rx and tx.
And finally 40m: This is exactly what I believe this antenna to be. A perfect 40 meter vertical. It is the best performing 40M antenna I have ever used! flat swr, and signals flooding through to full scale. World class performance with only a few watts and blows the other antennas away. Unfortunately not so of the other bands. How can I be the only one with these results. Its mounted in a clear spot on a hilltop with 100 ft of lmr 400 and I expected more but have not had the results mentioned here. Before the wind took the G5RV down, it was night and day better (reception) on 80. Never had an A/B to determine tx but know the G5RV always blew the longwire and R5 away for reception on 80 so I can base it on that. If anyone else has or had such reception with theirs I'd like to hear what if anything can be done to improve things.

After my recent review of December 27, Mickey, K5ML, contacted me with some encouragement. I went out in the snow and again reconfigured my balun into an unun and began experiments. I am now experiencing greatly improved DX performance on 80M. I am still feeding the un-un with about 40 ft of buried coax into a Palstar AT2K tuner in the shack. No more 80M tuner arcing problems, even at high power, although the 80M SWR on the coax is high, 14:1, as compared to less than 3:1 on the higher bands. It is tough to measure without a side by side comparision, but I am having MUCH better luck with working DX on 80. I have also found a tuner setting that will allow operation on 160M up to the 500 watt level. The coax SWR on 160M is very high, too high for my digital meter to measure, but I have made some 160M contacts with this configuration. The coax SWR on 160M before the change to the un-un was very low and very broad. A similar situation also occurred on 80M. This broadness was too good to be true on those bands and undoubtedly was because of inefficiency in the system, probably cause by the balun configuration. Even with the higher 80M coax SWR the system is now much more efficient. My thanks to Mickey and to those who figured out this modification. I am well pleased with the antenna. 73, K7UA
