Wow, that's pretty good going and so close to the model! I've used the same program and although it's been good, it wasn't as accurate as it is here. A really nice antenna and I'm envious of your tall trees! My trees are 35-40ft but still worth a shot. I was interested to learn that a rectangle brings the SWR down. Thanks for the video Mike! 👍😃
I really hate to speak of things so controversial as antennas BUT :) I once built a set of bi-square antennas for 10 meters Both on a single mast I am sure a bi-square has a bit more going for it than a 1/2 wave dipole I fed mine with 450 ohm line Well enough controversy for me I need to sign off :) TNX fer the great content You one of the very best in this genre 72
Nice video! It supports the videos by Peter VK3YE about oblong antennas. I've recently built them for 6 and 2m with similar success on a 12m tall Spider Pole portable setup. It seems like your approach is quite scalable for higher frequencies!
Great antenna choice for performance and simplicity. If you're restricted in height a quad will still give good results where other antennas will not..
Nice result.....but no trees more than 5 feet tall here... Again you showed that a loop is a good choice (I also lov to watch w1vlf's channel, he is also great). Thanks.
@@MIKROWAVE1 I watched again. It was a bit earlier than that but I see it now. Thanks! I'm going to run the top and bottom through PVC and secure it so it stays in shape and can be hauled up like a kite. Now that I have the ratio I can convert to any band for a starting place.
Your vswr is out of calibration on forward power. Measurement of the antenna's VSWR should prove to be lower than what you measured once calibrated. Timestamp 9:29 clearly shows power forward meter is generously showing output power of a couple watts with no power applied. The reflected power meter seems to be reading Zero as they both should. What you later claimed as 1.5 VSWR was probably really a couple of divisions lower... Where is the diddle driver in the desk drawer it's always hiding... 😂
@@MIKROWAVE1 That's great. How many bands can you stack? Do they have to be harmonically ..er.. related (Can't think of the right word.) 20-17-15-12-10m?
I love your antenna build videos! Thank You
Noticeably stronger 10m signals on the rectangle. Well done
Matched great and less noise on that loop as well. Getting it elevated to that height is also a bonus. Well done!
I love your videos. Some of the best Amateur radio content out there. You sir are truly helping to advance the craft of radio.

Video are great. TX antenna and a selection of rx antenna. 73s

Nice antenna realization 👍and simulation 👍

Seems like the SIRIO STARDUSTER M400 will work on 28Mhz as it is designed to operate from 26.6-30Mhz but us tunable.
Nice!
Thank you
Whatever modeling package that the DXCOMMANDER is using must be the right package.
So lucky with all the tall trees. I had to make masts, my wife is not impressed.
Basically it would be nice to know if there are roof lines or other places you could sprout an antenna (without erecting a moon-raker)
Magnifico vídeo.73 de EA7KKN
I love antenna lore (hallicrafter sx-71)
What a Long Wire antenna which is 1 mile long driven via an 9:1 UNUN
Nice result.....but no trees more than 5 feet tall here...
Again you showed that a loop is a good choice (I also lov to watch w1vlf's channel, he is also great).
Thanks.
Would you mind sharing the dimensions? I see it is center fed at the bottom. Thanks!
They are ¼ wl on a side for a full wave antenna, for a square loop. Ron W4BIN
@@W4BIN For a better match though is there a ratio of one side to another for the rectangle? What did your top wire end up being in length?
7.20 shows the dimensions in m and I convert to feet in the audio.

Basically 6x12 ft
You have a perfectly good tree and could have taken a leaf out of W5JGV's book and got the tree resonant on 28Mhz
You Nailed it! And then attached coax to the Nail!

Ah yes something that Burton used back in the day.
More antenna video's ! G7VFY
I just put this back up for the sunspots and added 15M to it off the same feed. Works slick.
