All us radio nuts must the same kind of story. Mine was a 25 foot telephone pole when I was 15. The wire ran all the way from my bedroom to the bottom of our garden, then over a narrow Access road to the back of our garage. To me it was a thing of great beauty, but I didn't take into account the garbage truck that called every Wednesday. It took the whole lot out. The pole was dragging behind it for about half a mile!

Yeah I had telephone wire for my antenna I ran the wire out the bedroom window to the center clothesline pipe to the one end and went back to the other pipe on the left from the window looking out the window. I didn't know you could feed from any part of the long wire antenna. My radio was an American 5 tube radio by Admiral. Good thing I never touched the antenna wire I may have got a shock. You cannot or should not put a ground on those radios. The one side connected to the chassis or buss in my case. The radio was cased in a plastic box. The chassis part was a bakelite circuit board. I also made the radio pick up shortwave by tuning the rf and if coils. No standard broadcast radio was safe around me. I picked up wwv and Spanish SW stations.

One thing to note for anyone that might build one of these at home... if the conduit you use is galvanized, you should either remove the zinc coating from any areas that will be welded, or, at a minimum, perform the welding in a very well ventilated area and with proper respiration/filtration. The Zinc Oxide fumes that are released when welding galvanized steel can cause some pretty nasty side effects. If you start to experience headaches/tiredness or other flu-like symptoms, stop and get some fresh air. If bad enough, the fumes can kill you. Galvanized pipe can be welded safely though if the proper precautions for ventilation/filtration/etc are followed though.

The antenna performs phenomenally well much better than my horizontal and is almost totally immune to man made noise. Because of the polarisation being vertical and most men made noise being horizontally polarised.

If you had drilled 2 holes trough the 2 inch pipe around 6-8 inch down from the weld you did then you could have welded it with 4 spots there to the 1.5 inch pipe to keep it more stable than the tape does. Back in the early 90's we did use this technique in the welding factory we had when welding rods inside pipes. Depending on the wind and future snow and ice hanging on your antenna wires it might hold up what you did there too, time will tell :) Nice welds by the way, looks good, looks like we did it.

He has videos on his cars, and so much more. In a few years, when I finally get ready to build my own Tube Amplifier, his projects on Patreon will be a mandatory for me. I'm no Bob Carver, but I sure like the fact that you can Build things if great time is taken, and with help of some great testing tools and advice. You can do it. I'm never going to be an E.E. But that's not the point. The education you are getting here is IMO, better then what I could get going to a college these days. No requirements to learn something that really has no basis in your goals to understand circuits you are wanting to learn on how to best work with them or in my case? *Troubleshoot* His videos have made me a better Low Voltage Tech. as many of the skills I use daily relate to some of the content he has made Available. His method reminds me of my History Teacher in Highschool. Coach Mac. Learn for the sake of learning. I can't say enough good things about just learning how things work. It really made me start to really appreciate the engineering that goes into audiophile grade items. And what to look for and spend my hard earned money on. on top of that? His videos are a JOY to watch. Being a person that is very critical of Sound Quality? Even in this video, there is no typical Microphone overloading that you hear so often from other creators. Its all top notch aft to stern.

Just so you know, there's another way to join pipes. What I've successfully done is overlap the two sections by maybe a foot or so, and add a third piece of pipe of similar size to form a triangle cross section. Fat dowel or wood closet rods would also work. Then I measure the circumference to buy the appropriate diameter stainless hose clamps. I use 4 in total hose clamps. Two for the top of the triangle, and two for the bottom. You can use fewer clamps, or more according to your own judgement. Anyway, tighten all the clamps enough so all seems solid and won't loosen. I have had zero issues with strength aside from not using large enough diameter pipe for wind load. That's not an issue with the joints though. The clamps never seem to loosen either, but you can still take precautions if you want to. RTV works very well as a thread locker, yet isn't very hard to break loose when needed. It's an old recommendation I read one time about protecting shock absorber threads from rusting on cars.

I did something similar only I used 1/4-20 hardware. I welded 2 rows of 6 nuts spaced 60° apart around the periphery, and each row 10" apart along the length, to each size conduit beginning with the 2" EMT. Then drilled through the nut and chased the thread with a tap. This made for a telescopic arrangement. I then drove a length of 1" cold rolled round into the ground and set this telescopic arrangement over top of it. With pre-cut down guides attached I went up a 12 foot step ladder and extended each section and locked it in place. Repeated for each section until the whole thing was extended. Spent about twice the time planning as I building. One 10ft length of each: 2" EMT, 1-1/2" EMT, 1-1/4" EMT, 1" rigid. About 36' high...

Anyway I was going to say you can buy 10' sections of fencing top rail that are great for antenna masts. One end is tapered so you can slide another section over it and it fits nice and snug, don't even need to weld. You could throw a U bolt clamp on if you were really worried.

For receive only I use a 3' diameter active loop antenna constructed from 1/2" soft copper and PVC electrical boxes. A low noise current amplifier is mounted at the antenna and fed with CAT-5 Ethernet cable. It covers VLF to above 30 MHz with excellent results. I have it on a rotor so I can find the maximum signal/ lowest noise for a given station. It works really well for nulllng out broadcast stations that occupy the same frequency for long distance night reception. A VLF or even BCB dipole at this location is out of the question.

Why not a double end-fed antenna? If you want to use at both house and workshop, both ends could be matched via a 9:1 UnUn, at both ends, each slightly offset a few feet within the antenna wire (assuming non-resonant, broadband receive-only usage). Run coax from the UnUns to house and shop, respectively. The coax shields will both add vertical elements to the antenna (assuming UnUns are an auto-transformer design). If not desirable, common-mode chokes can be inserted near the UnUns. To help optimize received power transfer, a tunable L or T matching network could be utilized between coax and receivers at both ends In effect, the above antenna configuration is a non-isolated ports, RF power-splitter design.

You should def. Grind the Zinc Galvanizing coating off before you weld. And have plenty of ventilation you dont want to breathe the fumes off of that . Cant wait till part 2
Cool project Paul. I’m looking forward to the next... Best, Don

I usually just cut a short bit of pipe and slit it longways, and use that as a shim spacer between the 2 pipes, ie, like what the tape is doing.

Thanks Paul. Right now I'm learning for my RF technology class at university. It's refreshing to see a video about actually building an antenna rather than just calculating/designing it. I love the "learning by doing" way so much more than just reading text books or ( as we do in university) learning the theory before making experiments. will it be just a normal dipole antenna? I think a Yagi antenna might be the best if you know the location and polarisation from the sender...

Ahhhh! I know what you are doing!!!! You are preparing for the winter snow season so that you can harvest some of that mysterious energy that you encountered last time on your workbench! We don't get snow here in Melbourne Australia! I would love to make an antenna out of a coil of copper wire in a loop so that the snow fall through it, one end tied to an insulated ground spike with only it's tip exposed so that you get a higher voltage potential difference between the antenna and ground spike tip! A switching circuit to pulse the energy to ground and a capacitor bank that gets charged via a diode which the negative of the capacitor is also connected to ground to complete the circuit! Such a pity that we don't get snow here, I would love to try it. This kinda reminds me of the falling water experiment that was done by (if I have correctly spelt his name) Victor Shouberger, there are a few videos here on KZitem that shows how it works, really fascinating stuff! I have always wanted you to follow up on that anomaly that you experienced! Who knows? Maybe one day that video will come!

Paul, this is PERFECT! I also have a long wire antenna in my garden, but it picks up so much (man made) noise, it is no fun any more! Since you also live in a residential area: do you also have a horrible noise floor coming from your antenna? Any ideas on what to do to help with that? Magnetic antenna instead?

You could use a decent sized hammer drill on hammer. to push the pipes together. Cut off a hammer drill bit off and weld it to a piece of 3"x3"x1/2" plate steel or something like that. I made an attachment to drive 10' ground rods into the earth with a 7/8' deep well (impact /black) socket, welded on to the bit. Hammer away
