ES5TV 15m 8x5 Elements H Frame Stack

70 meters high tower carries 8 5-element 15m yagis as pairs separated horizontally by 12 meter distance and vertical stacking is 14 meters. The heights of the antenna pairs are 64, 50, 36 and 22 meters.
Antennas are Optibeam OB5-15:
www.optibeam.info/index.php?ar...
Tower is produced by 4O3A/YT3M:
www.4o3a.com/index.php?option=...
Antenna has ca 16 dbd free space gain and over 24 dbi gain at 4 degrees over real ground. Beamwidth is less than 30 degrees. Testing confirms exactly the modelling results. Pattern measured with signal generator and SDR was almost identical to what the computer suggests and signal levels drop ca 12 db when antenna is 20 degrees off and already 20 db when 25 degrees off the correct direction. There is huge -50db+ null at 90 degrees confirmed with real measurements (!) and ca -20-30 db signal drop on the other directions.
The stack has phase switching capability which allows any pair of the 4 to be switched out of phase to change the radiation angle. Pre-configured steps are 4, 7, 10, 15, 30 degrees while maintaining most of the gain as all antennas are always connected

Super antenna! I hope it does well in the winter time with that Baltic weather. I am sure it carries a heavy ice load! I would be worried a little about ice in all those turning parts.

I think my jaw is finally back off the desk here. WOW...and congrats on that MONSTER ARRAY. Tnx for posting the video (also well done!).

I would like to see that tower turn in a -35 Celsius Canadian winter night.

[@Penn1969]

Incredible antenna system, congratulations. However, I do have to agree to a certain extent that you get to a point where you know you are going to be heard whatever the situation. A lot of enjoyment I get out of hand radio is struggling to hear a weak signal and persevering until you make the contact. But hey, I expect this is just a contest station. Can I suggest that the next job that you do is tidy your shack up, looks like a bomb has gone off in a spaghetti factory

[@AndrewMurphy8383]

lol and your look any better lol

[@johncliff5417]

Just great. A lot of thought has gone into this antenna combination. I just hope you do not get any nasty wind causing problems in the future. It just must be nice to have an antenna farm like that with no Anti Ham neighbours to moan about the masts. Very well done. 73 de John - G0WXU.

I knew this wasn't anywhere in the Southern United States when the next day that massive structure was still there. Here, a couple of meth heads with a pickup truck would have had the whole thing dismantled and at the recycling center before sunup. Seriously though, that was an awesome video and project. My mind boggles at the engineering and other talents that were needed to make this happen. Great job, guys!!!!!

Dream of Antenna

[@halkennedy6353]

Awesome acheivement. There are a few other very high gain 15 meter antennas around the world - a QSO should be possible. Some of the comments???? The timing is perfect. It's 15 meters - it says so. The meter shows 50 watts output, the gain of an ACOM2000A is 15 dB (you can look it up). That's 1500 Watts output for 50 watts input. All good. N4GG.

Very nice to meet you on 20 meters today! My station is far less impressive. 73, from K0KMH.

[@k0rc]

The guy wire clamps at 11:50 appear to be installed incorrectly. The "saddle" should straddle the live guy line. There's an old guy-line saying "Never saddle a dead horse" which means "do not put the saddle of the U clamp onto the dead end of the guy wire."

[@tonnovahk78]

you are right! I am in the middle of fixing this to be on the safe side. Thanks!

How tall is the tower?

[@tdx54]

Hi Tonno, could you relive some technicalties, i.e.stacking combinations, steering angles, overal gain of the system ? Guess, it would be between 14 to 16 dbd ? Guys, great job, who the hell said, antennas are not beautifull :) Kr Nermin S58DX

i don't know:) Viljo, ES5PC, picked it. But it is quite nice indeed:) It says something about the author at the end of the movie.

[@dave858man2]

how do you match up those antennas? I thinking on doing 4 cubical quads in that same smaller configuration. not sure how to co-phase them though. any help would be appreciated.

[@tonnovahk78]

Hi, I use 1/4 wave coaxial transformers to bring the feedpoint to 50 ohms.

[@dave858man2]

I am new to co-phasing antenna's. is there some place I can get information on co-phasing 4 antennas. ie the turn ratio of the transformers and the impedance of the phasing coax etc. thanks for your response, that is a very impressive array you built. I'm planning on putting 4 cubical quads in the same but smaller setup as you have

[@tonnovahk78]

I am using simple 1/4 transformers: en.wikipedia.org/wiki/Quarter-wave_impedance_transformer It means 2 pieces of 50 ohm 1/4 wave cables in parallel to bring the impedance from 12.5 ohms back to 50 ohms. No turn ratios or any other fancy stuff. If you hhave 4 antennas with 50 ohm impedance then this is what you can use to bring the impedance back to 50 ohms from 12.5.

Do you still have the engineering plans for the concrete foundation and pivot for the rotator I like to do something similar?

[@SocialistDistancing]

OK correct me if I'm wrong. 24db antenna, with 150w pep, would have 37,000w output. Unless I did my math wrong . If that number is correct, that's crazy. I can't imagine how money that array cost.
