great 1:2 UNUN for inverted L antenna Time Owned: 0 to 3 months.
I made an Inverted L antenna for 160m, grounded by 32 radials. Resistance about 15 Ohm as predicted. I tried hairpin matching and this lowered SWR from 3.7 to 3.0

With the help (super fast reply from Hugo) of an ON7FU 1:2 UNUN I was able to achieve a resistance value of 49,5 Ohm and an SWR of 1.07 ! In fact it is an 1:2.25 transformer, perfect for matching Inv L with radials.

Played in the CQWW CW contest with 1 to 1,5 KW for more than 20 hours. Stable SWR, no changes caused by heating and an excellence performance.

More details of the antenna construction on my OT1A blogspot site.

Great product again !!

1:1BALUN Time Owned: more than 12 months.
3000W 1/1 CURRENT BALUN for wire antennas.
Very satisfied with the product and very good service by Hugo ON7FU.
Get very good reports also outside of Europe on the low bands.
Definitely recommended for that top product.

4:1 BALUN. Excellent Time Owned: 0 to 3 months.
Having had the big 100 ft tower with huge beams etc, it was time for me to go back to basics. I stumbled upon an article by ON4AA about OCF antennas using a 4:1 balun and I contacted Hugo ON7FU who proceeded to manufacture the balun I needed. It arrived in about 2 weeks. Excellent workmanship, sturdy construction and excellent customer /after sales service. The balun works perfectly with my 1 KW of power. I am very impressed with the results.

Great product! Thank you Hugo.

for years then don't wait to buy those baluns .
The 100% watrproof up to 3kw in serveral versions .
I m a happy owner of on7fu baluns .
I run thel on a 40/30 optibeam a 60m dipole a 80m dipole .
And a inv L .

Good building quality and technical specifications! Time Owned: more than 12 months.
I am using an 9/1 unun in combination with a random wire (circa 18m ), feeded 3 m from the end.
On most of the HAM-bands, it is possible to achieve a low VSWR with the internal antenna tuner of my transceiver.
There is no noticeable heating of the unun during longer periods of transmission (100W). Mechanically is the unun nice constructed. It is built to last for many years!

ON7FU: Perfect quality and excellent service! Time Owned: more than 12 months.
For my new OCF dipole I needed a 4/1 current balun and a coaxial line isolator.

A market study yielded a large number of offers. But there was only one supplier who was completely convincing with the professionalism of his offer, the quality of his products and the perfect customer service. That was Hugo, ON7FU! So he got the job.

And a year later, he's still willing to answer swiftly general technical questions by e-mail.

Thank you, Hugo!

balun/line isolator, so much more than an optional accessory Time Owned: more than 12 months.
Over the past years, I have purchased several types of ON7FU balun products: 1:1 and 1:4 balun, as well as his more recent ‘hexbeam balun’ (with a pigtail) to replace the standard one with a high power version.
You don’t want to bring down a hexbeam every year to replace a faulty component: it’s a nice antenna but a pain to get on a tower, and the balun is mounted completely at the top.

More recently I purchased a couple ON7FU coax ‘line isolators’ to manage common mode currents to reduce 'man-made' noise introduced from the surrounding (incl my own house).
In my particular condition, the use of a ON7FU’s line isolator (which provide high enough choking impedance on HF) reduced the noise level with a couple of S-points. It is as if you give a 1kW linear amplifier to the other station… Too few people realize the usefulness of using baluns and line isolators to choke potential RF common mode, not only to reduce RF feedback but to actually reduce noise on receive. Even 1 S-point matters for some communications.

The ON7FU balun’s are professionally built using high quality products, from the enclosure to the coax that is used and wound on the ferrite torroid (which is of the right 'mix' for your frequency range of intrest).
Get yours, you will not regret it.

Hexbeam QRO Balun + Inline QRO Balun Time Owned: more than 12 months.
Excellent communication with Hugo. I’have buy one QRO Hexbeam Balun few years ago. Very well made. Still on my second Hexbeam after 5 years and work fine. After few years I buy a second one to replace my Bencher Low Pass Filter for Hugo’s Inline QRO Balun (3KW PeP), so I don’t need anymore to remove the filter when working on 6m. The PL259 from the pigtail balun is directly connected to my PA ACOM 2100 and the coax from the Hexbeam to the Balun SO259. I recommend you his products *****

Outsdanding Time Owned: 0 to 3 months.
I am a new addict of the Top Band 160m and I live in a rural residential area and had a lot of noise only in 160m, after 2 years of trying to find out I managed to find the source of the noise problem, automatic led lighting of 2 neighbors, I changed the 9 of 1 and 2 on the other, the noise dropped from S9+10 to S7, not happy because I have S 3-4 in 80m, more research I found Hugo and very good and honest information on his website. I sent an email before Christmas and before the new year I already had its line isolator. My friends, very good product, at least 2 - S units, now I have 4-5 noise in my 160m double bazooka. There are no arguments against facts.
Hugo is the Man for highest quality Baluns,Ununs,Line Isolators etc.. . 11 stars is little.
