An appropriate subject for this wee's live stream. I just got my General ticket today and I'm planning on delving into HF.

KJ5AJP put 4 used utility poles up, one each corner, then a full wave loop for 160m, it will also tune higher bands... Direct bury coax is a gopher snack... something to keep in mind! Found that out the hard way! Little rodents even ate the jacket off my FSJ4-50b hardline! I now run everything in conduit... Amerite 25g clone 6' sections go UPS or Fedex... house bracket top and middle of tower, tilt up base plate to walk it up... 6 sections gets you 36' can do it all around $1k minus concrete costs Telescoping mast and house brackets! Local steel supplier, get 10' sections of 1/4 inch wall steel that slide into each other, start at 3" and go thinner until you hit 2". Can weld or bolt sections then house bracket at eave end of house... that was my first antenna tower that held a 2 meter quagi! Rotor was arm strong method with a pipe wrench! Heavy duty rotor Spid Big Rak for $2k. I gave up on other rotors, I killed a Ham IV that was turning a 6m and 70cm yagi, the winds here are extreme and it shelled out the spur gears off the motor. I have killed Yaesu G800's, same issue, eats gears... I now have 5 Spid rotors, zero failures, they are built like tanks. KF7P Metal Works has the best US price on them!

If you parallel a power line with a dipole or endfed, you'll get a lot of noice induced from the field around the power line.

HRCC, the question should be: "Which antenna should I build"???? Buying things 'off the shelf' should not be an only choice, to get Ham Radio on a budget, you MUST teach how to make your own for Hams to understand how antennas work. There is no other way to learn antenna theory !! I tell you how, and you 'might' learn, but if I leave you with the way antennas work and you build one on your own, then you will understand how antennas REALLY work. My Elmer taught me how antennas work, and I have retained that knowledge over years of Ham Radio. Teach them how things work, or you will fail them all.

Not everyone wants your level of knowledge. Nor must anyone be forced to build antennas to attain that knowledge.

@@ynot6473fun is completely subjective. There have been times where I spent several weeks configuring and reconfiguring a single antenna just to see what the changes would do. Most people are not interested in doing that. Most people want something that is optimal for their space at the most convenient price. We can't put those people in our box. They don't want to be there.

I agree. But saying people “MUST” build their own antennas is more gate keeping bs.

Am I crazy? My home is on a 50 x 100 lot (No HOA) plus Canada has court rulings stating 15.25 meter support structure not including booms masts and antennas are exempt from town planning scrutiny so putting up a US Towers tubular crank up MA-55 it will be kept at 45 feet except for contest weekend where it will climb to 55 feet. Putting 2 Crushcraft 17m boomers (11db each), with a MFJ multi band rotatable dipole (MFJ-1775) & 2 AREDN nodes between and a Diamond 2m & 70cm 10 feet over the others. HAM 4 rotator Feedlines are LMR-240, as I have a roll! I also have a Crushcraft A3S, HF BEAM 3 ELE.10/15/20 METERS, 8.0 DB and a 56 foot Delhi tower and several CDE HAM 3 rotators and a Tower trailer with 32 feet of tower which could be fun for POTA.

Why not a horizontal 80m skyloop? I installed one, the noise floor at my qth came down a bit, and I can 'hear' and 'get out' better. I run 75 ohm catv cable directly to it, np unun or balun. It's about 275 ft long in an odd shaped triangle, one corner is about 60ft high, one corner 35ft, and the third corner 25ft. It beats everything else I have tried including vertices with 62 radials, raised vertical with 4 raised radials, all sorts of dipoles, endfeds, etc. They are cheap and just work.

@HamRadioCrashCourse No, not laying directly. Probably strung right over it from one tree to another tree, clearing the highest part of the roof by around 7ft.

Lowest spot 7’? It’ll affect pattern, but will work as an antenna.
