Exceptional antenna!  Time owned: 0 to 3 months
WR3KI beat me to it, "Works so well, this antenna should be Illegal." Guess I'm the outlaw DXer then.

I've had my 43' 160-10 ZeroFive vertical up just at a month. Went together like a breeze. Started with 8 radials in the ground. That was taking forever so went the lawn staple route and now have 73 radials down, ranging from 30' to 43'.

No real technical reason for 73 (3000' of 14 ga. copper braided). More caprice than anything but it sure does work well. VERY well! I can hear stations all over the world now that I could not before AND WORK THEM. Have made (in this first month) 328 QSOs as of this writing. Already had DXCC but getting new countries fast.

I've a ham for over 53 years now and had many good antennas but the ZeroFive is a GREAT antenna. Highly recommend but do not get chintzy on the radials -- the difference between 8 and my current 73 is fantastic. Tom, the ever-helpful guy at ZeroFive, told me at least 48. So lay down the copper.

Does the job, looks impressive, reaches out and pulls the DX right into your shack and practically fills out your log and brings you coffee.

Did I mention it's a GREAT antenna? It is.

So Good, Should be Illegal   Time owned: 3 to 6 months
Picked up a 20 meter 1/4 wave vertical from ZeroFive a few months back. Got around to putting it up last week. Went together easily. Well made.
Mounted out 60 feet on the pier, out in the Chesapeake Bay. Two raised radials, both slope down at 45 degrees. Antenna is mounted on a 5 foot mast, bolted to one of the pilings. PLUS, connectivity of the antenna base, to the salt water of the Bay. Up once, took measurements with the 259B, and then made adjustment, & everything fell into line. 36 Ohms at the feedpoint, & flat swr at 14.2. Started making contacts all over the planet. Works so well, this antenna should be Illegal. In fact, plays so well, thinking of putting up another, & phasing them, in a east -west configuration. Overall, excellent product, went together easily & works as advertised.

43' Vertical 10 - 160M with 5KW UnUn  Time owned: 0 to 3 months
Let me say this is my first experience with a ground mounted vertical antenna.

I have the Zero-Five 43' 10 - 160M Vertical Antenna (Fold over Ground mounted version) I am using 100' LMR-600 + 34 Radials -> 43' to 520' in length. I have run her with the Balun Designs UnUn and the Zero-Five UnUn (supplied with my kit) I also Added 4ga insulated cooper wire attached to 8' ground rods @ 43' and 16'.

I have tried her with a Balun Designs 1115DU Isolation Balun (which seems to work well with this setup) I have used her with external manual and auto tuners as well as the factory tuner in my Icom 746Pro.

First let me say that the Zero Five 43' fold over antenna is very well built. Assembly is easy with one person (Much more fun with a YL) Height above ground is critical and varies with site. It should be said that she won't operate without radials.

There is absolutely no comparison to a dipole, loop, or good end fed wire multi-band antenna! Total cost and installation time are triple +. Comparison Gain on this antenna is pretty much a flat Zero.

While advertised as a multi-band Vertical she plays very well on 40M, does good on 20 and so-so on 80 Meters. Useless on most any other bands with losses of up to 90% on the higher frequencies. 160 Meter TX performance -> not happening. That said 43' should do really good on 60 Meters if that band opens up...

I began this project to keep the YL happy (not so Y at our age but much more fun!) I think for someone that uses primarily 40 Meters that has a small site, no trees, etc. it might be a good choice. For reliable DX operations there are far better antenna choices in my honest opinion.

I'm still looking for a site for my dipole that will keep the YL happy... in the meantime I may buy/experiment with a second Zero Five antenna to set up in a phased array (directional) using this antenna as the primary. I will report back if I do.

I give Zero-Five a Big 5 for Engineering, construction materials, initial cost, and time/ease for installation. There is absolutely no comparison to many 43' antennas on the market IMHO.

I give 43' Verticals in general based on my findings; a solid 2 as a multi-band antenna and a 4 as a 40 meter antenna.

I hope you find this useful.

R7 Base Assy Rebuild  Time owned: 0 to 3 months
The fiberglass base insulator on my venerable R7 had deteriorated and was beginning to disintegrate. A repair using Rescue Tape fixed the insulator exterior, but not the worn out insulator itself which had become wobbly.

ZeroFive's rebuild service for these antenna base assemblies is excellent. The only original parts used in the rebuild are the matching network and brackets, the bottom hat brackets and hardware, and the mounting rings and hardware. Everything else is new and of outstanding quality. The rebuilt base assy is mechanically superior to the original by a degree of magnitude, both in materials and design. The rebuilt piece is far more rigid and mechanically elegant. The heavy main insulator is bullet proof, and the first foot of tubing above the insulator is double wall. Customer service and turnaround time were notably excellent as well.

If your R7 or R5 traps are still serviceable, I highly recommend this rebuild service.

Fast repair service!  Time owned: 0 to 3 months
Tom rebuilt the base section of my Cushcraft R-7 vertical using oil impregnated nylon material as the insulator, provided new upper and lower tubes, all hardware, and mounted the matching section to the new base. This nylon material will far outlast the original fiberglass used as an insulator. I can't wait to re-build the antenna and get it on the air again. Quick and easy communications with Tom, and great turn-around time.

Best vertical I have used in 48years  Time owned: 3 to 6 months
I have been involved in Ham Radio for over 48 years. I have used many brand name as well as home-brew verticals. We sold our home and almost an acre and a half of land with 90 foot freestanding tower and antennas from 160 meters to 2.4 GHz and moved to a condo. No towers or attachments to the home are permitted. I have wire antennas 15 feet above the ground in the crawl space that cover 75 through 10 meters. They work but pick up a lot of noise.
I purchased tom's 30 foot Flag pole antenna and what a pleasure. It is by far the best constructed vertical I have ever seen. It came complete with everything necessary except the radials. It outperforms my dipoles in the crawl space in most instances. I have 28 radials ranging from 14 feet to 33 feet in length. I have plans to install additional longer radials. I mounted my antenna in 4 feet of concrete 12 inches in diameter. It should be noted that the antenna came complete with Flag and Halyard. I plan to post photos on my web site soon.

40 METER 1/4 WAVE FREESTANDING VERTICAL  Time owned: 3 to 6 months
DX pileup buster.
Europe and Australia is an every day occurrence even with marginal band conditions.

I own this one:

I use this feedline current choke to reduce ground loss resistance:

I did not install any ground radials for this antenna.
Depending on your particular installation, your location and the condition of the soil surrounding your antenna you may or may not require ground radials with this antenna.

Custom 20 meter, 3 Element, Full size monoband , 5KW Yagi  Time owned: 0 to 3 months
I talked to Tom, asking him if he would design a High Performance, 3 Full size elements, very heavy boom, 5KW rated, Yagi. I needed this built to withstand 100+ mph winds. And if he would build this would he build this like he was building this for himself! The answer was Yes! This is the very first, 20 meter monobander built by Zerofive Antennas! The boom is 18.5 ft. in length, boom dia. 2 1/4 inches, 1/8 thick, and the ends of the boom are 2 inch, 1/8 thick. This Yagi 3 Element beam tested, at 14.150 to 14.350, at 1.1 all the way across the 20 meter band width! The wieght of this Yagi is 62 lbs. f/b ratio is 24 db gain, with a forward ratio of 7 db gain. Wind surface load is 6 square ft. Turning radius is 22 ft.and the power rating is 5KW. All the mounting u-bolts are 3/8 inch dia. I,ve made several hundred contacts on 20 meters know, and this antenna works Perfect! Most of the contacts, that I,ve made, are outside of the United States, using 100 watts or less power, the reports come back with a 20 to 40 over S-9 report! I turn this Yagi and a 10-40 meter zerofive ground mounted verticle, with a tail twister rotor. This antenna is the very first monobander built by zerofive and can be seen on Zerofive Antennas web. site. All of Tom,s monobander yagi,s are Custom built one at a time! Very happy with Tom,s service, and what a great guy to talk to on the Phone! Thanks

Quality built  Time owned: 0 to 3 months
I'm joining the choir here when I say that these verticals are pure quality. So is Tom.

I installed one of the 20-meter monoband verticals. Even with the rave reviews here (which helped me make my buying decision) the quality of the antenna is almost shocking. This is one sturdy vertical - overbuilt in the nicest sort of way.

Assembly is easy.

I ground-mounted my vertical, following Tom's directions (he answers e-mails almost instantly and also offered fine advice about radials by phone).

So far I just have 32 radials down - I'll probably add another 32. The antenna has been operational for just a few days but I've already worked several DX pile-ups with 5/9 reports.

I once used a Pro Mosely - no tower, no beam now - and it isn't suprising that a 1/4 wave vertical is not equal to a yagi. What is surprising is that in many cases I see no difference. I've used the vertical both with and without the linear and it seems to hold its own with most competing stations when working DX. I've (literally) never had a report below 5/7 and most are 5/9 or over.

Tom himself lives up to all the rave reports here. I'm glad I bought the 20-meter monoband vertical and am already planning to add the 40-meter monoband vertical and take my wire antennas down.

Built like a tank and performs great!  Time owned: 3 to 6 months
I replaced a HF6V with this antenna and was stunned at the quality of workmanship and the strength of the material used. It went together quickly and there is a noticable difference in performance over the HF6V (when that antenna wasn't broken due to the doorknob capacitor).

The owner is a great guy and will do whatever it takes to help you.

But this antenna!
