How does one compute the reflector length and distance start point for empirical testing 2-element yagi? Various calculators give differing results.

The biggest concentration on any one technical topic since Albert Einstein breakfasted alone.

Very awesome setup, well done!

wow Steve, glad to see you came out unscaved, see you on TB. zs2cx

Steve, thank you for your contribution to ham radio community worldwide! 73 Nick VK9DX Norfolk Island

"tunning"?

Thanks Steve, I built your design and have it running with a 1900ft Beverage in Ireland (on a public kiwiSDR as well (EI5IN)). A MW band bandstop filter is the next project though as the signals are incredibly strong here.

Great video. This has been a point of fascination for me for some time but I’ve been too lazy to break out the books and it’s a topic you don’t see covered in good detail on RUclips. I especially like the way you showed how the parallel nature of the impedance compares to a purely resistive circuit comprised of two resistors in parallel and applying Ohm’s Law. When you say grounded, do you mean electrical ground (via grounding rod) or RF ground (via radials)? I’m assuming the latter, but would like to know for sure.

Great content, well presented. I usually have to listen a couple times to take it all in. It's changed how I go about tuning multi elements antennas. Thank you for the valuable information.

Steve, de ZS2CX , was smiling all the way while watching your video, ....on 80m phasing 2 verticals back in 2006 to 2013 , was a dx hunter antenna and really worked well, back then (mfj analyser days). i remember having to tune on 3.7 to 3.750 Mhz ....with mutual coupling it bump the freq up to 3.795 (the dx window).. also this new found 4 radials elevated system did not work for me back then... i live close to ocean salty marsh environment... matching was needed just like your system, i needed N/S and broadside so my phasing was easier than having 4 verticals, but then i mean i live in ZS far south on the edge of our continent, so, latenight, early mornings contact worked for me, early evenings hardly ever produced any contacts (dx wise).... zs6ha Jan (sk)... used to join in on the fun , we nailed EU on a daily basis,Zl1iu now and then, with the usual flutter from zs to ZL.. greenland was a tough one too, had to break the Eu pileup... but we nailed it too. vk was easy as pie, ribin VK6LK (sk) was on every evening (sked) with non existent signals on a dipole, the verticals brought the contacts home. regards Johan zs2cx

Excellent. Glad to see your success. I have used quite a few BOGs since about 2011 when I moved away from my salt marsh location. (Beverages did not work at all over my salt marsh ground but everything else did!) My first one was 225 feet pointed NE and I expected to increase it a bit but it worked so well I left it. I also had one pointed West that was about 480 feet. The directivity was amazing when I switched between them. I also had a more conventional Beverage pointed South. I found even shorter BOGs worked reasonably well. I currently have one about 200 feet long pointed West and another I roll out across the backyard pointed to Europe each winter. Like you I use short ground rods at both ends and about the same value terminating resistor. 73, de Don, N4DJ

I hope you can save as much as possible of the tower for future use though. 73's Patrick - OT5Q

Brilliant again Steve, I have learned a lot from watching your videos on this, thank you.

Steve - another outstanding video that is informative even for non-engineers like me! How many ground radials do you use per vertical? Thx and see you on the air soon!

Thank for this nice explan how this works together !!! Thank you vy 73 DL1AQU Michael

As always a great video. Can this method be used for an elevated radial system ie 4 radials per element instead of the extensive ground system? John Limanowski N9DNB

4:00 "...resonating like a *pitchfork* ..." Lest any musicians or farmers be confused, I'm confident that Steve meant 'tuning fork'. 🙂 !!!

As always, a great and very informative video!

Brilliantly done. Many thanks Steve. 73 OM

Ok i heard now No longer using bog on skimmer but a short dipole.

Hello steve Greetings from Philippines Its 6pm locsl 23 nov 2024 Listening to 160m static crashes No copy on cqww cw contest any Station Interesting video FYI Ive tried LOP K9AY and BOG Bog seems only thing helps At mountain shack Your skimmer receivers using bogs What azimuth though Your using 300 to 400 ft ? Most use 200 ft 73 bob du7et

Thank you for your excellent, well presented videos, Steve. They are an inspirational to many of us who always wanted to get on Top Band! 73 from VA3DM

Great video and easily understandable dialogue as always. Glad to see your 160 setup is back on the air. What are future plans for the tower? Replacement or is an upgrade in the plan?

Excellentent presentation and execution. "Hatching a plan, modelling, design, engineering, validation, build, test and then validate. Why cant the ARRL Handbook and QST present projects like this that is professional ham engineering and technical skills at its best? It sure beat s arguments on reflectors, egos, fights and nothing achieved. A good example of putting your design money where your brain and mouth can do the job with professionalism.

Bugger what a birds nest you have some damage their big cost to fix time But HAM RADIO is worth it Wish you all the best on the repairs

Hi Steve, absolut great video !!! You have made a great explanation about the function of your antenna system !!!❤ Powerfull job !!! Vy73 DL1AQU Michael

Thank you for great explanation of this systems. Hat off !

fantastic real fantastic station 73 from kb2uew

Outstanding work . I am very curious how you tune the parasitic elements and how you determine the frequency to tune them. John Limanowski N9DNB

This is some really cool stuff! Thanks for sharing!

Fantastic video Steve! Thanks for sharing! I have to ask. Why do you use several 0.5 uH inductors instead of one 0.5 uH, one 1 uH, one 2 uH? That would give you more combinations with fewer relays. 73 Joseph VE3GKT

Excellent engineering Steve. Bravo!

Your preamplifiers work like a charm, and so does the transmitter to fly under a drone. Thanks for another great work and those informative and helpful videos.

Excellent work!

Unhealthy amount of jealousy!

That’s awesome

Hello Steve! I hope you are doing well and I thank you in advance. My name is Luso, one of your Brazilian fellow viewers and I am currently studying for my master's degree in Electrical Engineering, more specifically in the field of Antennas and Electromagnetism, even though I'm not originally from a background of electrical and electronic systems. I recently saw one of your videos on the design, construction and operation of your remote station and I felt really interested in the whole idea. The reason why I am contacting you is because I'm planning to build my own ground-station however to operate with satellites, in frequencies such as Ku and Ka, but I have little to no experience on the design process of a ground station and would like to know if you could provide me some information of the process, or even recommend more of your other videos so I can start developing my own project. Some of the topics that I would like to discuss are the operating costs, how much power it consumes over a month and what were your biggest challenges in building your station.If you are interested in my background or want to discuss anything specific in a video conference, I would appreciate it! Just tell me when you are available and I will schedule around it. Best Regards, Luso!

Wow!!!!! Glad you're ok and what a mess!!!!

fantastic presentation!

Excellent explanation. I'm curious about your suggestions of "other attena approaches" are to help alleviate distant qrn? 73

Is there a software to acquire signal strength from a SDR and plot it on a graphic? If not, what would be the best approach?

Wonder if anyone has actually modified a toaster (NOT toaster OVEN), to reflow boards... Thermal mass wouldn't be a problem, but no idea how boards and components would hold up against the direct radiant heat. Would probably need a good control system.

Steve, thanks for sharing. Yes, we have all made mistakes but we have all learned from them. Nice work though and sh*t happens. It is the Canadian way! 73, de va3mw

Whew. Glad you're ok! New safety rule: don't be within the "drop zone" when it is moving.

Hi Steve, just implementing this neat solution on my shack! For the 9C array Combiner box you run an independent/dedicated power source 12v DC line correct? Also I see you inserted jumpers to connect the 3 relays in the C port and another jumper from 4 to 8...am I seeing this wrigth?

I had a similar problem on my 15M two stage tower, a section of the wire rope that is normally not visible around an upper pulley developed a bad spot of rust and fractures as I was lowering it. Luckily it didn't fall anywhere as far as yours, yes tower damage, however the antenna's were mostly unscaved, although not quite as straight as they used to be, I didn't have any 'aluminium rain' I live in a suburban block, so no massive HF beams that would hang over my fence line. VHF, UHF & the centre for inverted V style HF wire antenna's, and a camera - So I can literally say "I'm looking at you" as I swing the beams around. Paul VK3TGX

I think the main lesson learned is actually a lesson re-learned - familiarity breeds contempt. It is too easy to not inspect everything thoroughly after a windstorm, and we all know it is a bad idea to be up in the air on a manlift while the tower is going up, especially without having spotter. "It's been fine for decades, so it is fine today" is the same as "I have always done it this way and never had a problem with it." Glad you are OK, and glad you shared this. We all need these reminders occasionally to keep us from getting hurt by our passions.

My condolences, I have found from experience that the consequences of failing to manage gravity's influence is proportion to the amount of investment and effort put defying it. You learnt so much from your experiments time for a new project. 73 G8WOF Wirral UK

interest is to learn from your misfortune not denigrate you...at least that is my take...thank creation you are well as an outcome. Dale KC7IVJ

Awe, nothing a pair of pliers and a can of silver spray-paint can't fix! I was also thinking you might have lost the base; I've heard of HyGain 70's crashing into the base. Wow, sorry for your loss (probably worse than losing some friends--LOL)! Anyway, so glad you weren't injured. For me I'd replace it but I understand well you point. I think this video was the first ever recommended, so at least you're for sure getting new viewers! So, SUBSCRIBED!!! Good luck on your new project and the very best to you! 73...
