Clear, concise, to the point. Great instructional video. I currently use to delta loops, apex up; one for 40 and one for 80. Both are vertically polarized, fed 1/4 wave down from the apex. Both are excellent DX antennas. 73 Jeff - W3AAB
I built a 20m full wave delta loop configured as #4. It is "portable" as it is made with two 7.2 meter fiberglass poles, a pvc tee, two 45 degree elbows, and some pvc tubing. It's schedule 40. I have it mounted on 10 foot piece of chain link fence top rail. I have a home made 4:1 at the feed point. It is resonant on 20m, and I can tune it from 40-10. Works best on 20-up. I am very happy with it, it works great on 20m.
Great videos! I have so many trees and just discovered the sky loop and the delta loop this evening and found your channel. And, I'm really enjoying your videos. Thanks for explaining all this so clearly!
@@HamShackReviews One thing I was confused about. Is this one long wire with insulators in each section. Or, is each section cut and attached to the end insulators? Again, thanks for your videos.
@@thequarantinecatholicLoops, almost always are one continuous wire which are passed through ceramic or plastic insulators. One wire generally speaking is stronger and less prone to break. If wires are soldered or joined together to form a loop, then they tend not to be as strong especially if used for larger loops. Certainly many hams do use joined wires though.
Vince, I want to try my first Delta Loop. My thought is for 13 Colonies Special event coming up. I have 450 and 300 ohm window line. I also have three 23 foot poles to use for raising antenna up. I have 10 watt QRP and tuner if needed. Going for CW too. Would you recommend a best Delta Loop for me in Maryland for 13 Colonies Special Event. Thanks N3EIE.
I use number 4 and would recommend it to anyone for DX, since 13 col. is stateside I would suggest number 3 as the easiest to install. Number 1 works nicely also, you will need an antenna analyzer for tuning.
For about 10 years I have been using a NO. 5 fed with about 20' of homemade ladder line, that is only used to span the distance fro the loop feed point to a remote and automatic MFJ tuner in a weatherproof box.. I chose a 40m size because that is what fits in my suburban lot. It is supported by a 34ft. fiberglass telescoping mast with non-conductive rope guys. This antenna surely isn't a sky warmer and works great on 60m-6m. It also works well enough on 80m since I have been successful using it on the winter time 80m qrp fox hunts that span coast to coast to coast. When chasing SOTA and POTA and if possible I start will 5w which unless the other station is very weak, I can usually make the contacts. If the station is northwest along the direction of the wire, I may have to switch to my broadband hexbeam at 12ft which beats the loop by a noticeable amount. I recommend it to all who have the space if they need one multiband wire. The MFJ tuner has a 4:1 balan and I have tried it and an elecraft 2:1/4:1 and really cant tell a difference with those and none. 2 weeks ago my loop was destroyed by an indirect lightning strike so I am thinking of building two 90deg angled loops that will also double duty as the mast guys. I want to try interesting and multiple feeding options including adding the total lengths of the two 40m deltas to forma strange 80m antenna.
Sorry to hear about your loop, but what you are proposing to build sounds very interesting. Please come back and share your results. Maybe we can even make a video using zoom.
Hey Vince,a few questions about the Delta loop. Since I want vertical your number 6 configuration for 20 meters. Is the quarter wave stub length 70.7 divided 4? My balun will be 4:1 current balun and I want to run 450 ohm window line from the antenna to the balun and coax short run. Is this a good configuration? The 450 ohm line will be perpendicular to the elements. Fed at the top right side for vertical
I am not sure of the math without figuring it, it would be dived by 3 since the delta loop has three sides. Leave the wire a little long because it is easier to shorten it than to add to it. I put the flat side in the air and fed mine at the bottom point directly directly with the balun(2.5:1 and no ladder line). However, my square loop was fed with ladder line down to the balun. It created two adjustments with wire length and ladder line length. Both work great.
@@HamShackReviews wouldn't the window line make it more multi band and mechanically not so heavy On the wire at the .25 wavelength location? Thanks for your help. I put the flat on top because of my yard location.
Vince, your Delta loop antenna drawing #6 where do I put the window line for vertical polarization ?That is the only configuration because of space. So the flat top is #6 drawing. The loop is up and down not horizontal with ground. Thanks for all of your ideas. I will let you know what happens. I like the balun design equipment,but I can't afford right now. But I will be using a 4:1 balun because I want multiple bands.
hi im doing the multi band one with a 4.1 ballun instead of 11ft each fibreglass pole and 11ft across the top with 33ft of wire could i use 13ft each side, would it matter. so its three sides of 13ft
I never built one that small, Use the formula to figure the wire length for the lowest band you plan to use it on. Come back and share your results with us.
@@josediaz-tq5cz It will work if you build an antenna with 50 OHM imperence. The delta loop has a 120-125 ohm impedence and that is why the 2.5 - 1 is needed. An antenna with 200 ohms needs a 4-1.
I learned more about Delta loops in this video than reading about them for 2 years. Thanks partner!
Glad to hear it!
Found this video while researching loop antennas. Solid info. Thank you so much.

When trees are used correctly they can be great antenna supports. And with the added benefit of being stealthy. I am happy you like the videos.

Figura 1 es polarizacion vertical.
Figure 1 has vertical polarization.
Yes, that is what the thumbnail says.
picture 1 should be vertically polarized
or figure 1
You are right, thank you for bringing it to my attention. Fixing it now.
@@HamShackReviews vertical polarization for #1, with a very low angle of takeoff....great DX antenna.
and 4 is vertical@@Dreamlgider
Where do I find the 2.5 balun
Balun designs makes a nice one, I have two of them.
I live on 30 acres of wooded alabama land .wires going over all the property plus my guard 💂 dogs 😮.
Very nice
Good...mt
What size balum for 11 m?
The same baluns work on 11m, The length of the wire antenna elements will be different.
