Further Notes on the Delta Loop

Waiting for the parts to arrive has taken some time, mainly I suppose because Christmas got in the way, but at last all the bits have arrived and I am able to continue the build with the Delta Loop.

Assembling all the parts on the main lawn also took some time but this was due to the weather, I wasn't going to rush when it's pouring with rain. Finally after a bit of patience we got there and the poles were fitted, the element wire pulled through and the ladder line measured and fitted and finally placed on a short piece of scaffold pole and up she went.

Just put up before dusk!

I must admit I wasn't expecting anything terrific first time, I hadn't tuned, played or tweaked in any way. But I tested on the FT1000  just to see if I could receive and get out. Well blow me, I got a result straight away. Measuring against the Hustler it was very quiet I almost thought it wasn't working at first it was so quiet!


A little closer

Using the Hustler I found a reasonably loud CW station then switched over to the Delta Loop. First impression was the background noise from a vertical like the Hustler was gone, although it was down an S point most probably due to it being so low off the ground.  I hadn't tuned or played with it in any way, so I could probably tweak it for better results plus I'd been using the auto tuner from the FT1000, not the manual Tokyo 400L. 
For a quick home brew job I was pretty impressed.
The next thing is to raise it a bit to give it some height, see if that improves it being down a S point to the Hustler.

Now I'll let you in to a little secret, a few days ago sitting talking to my Brother in Law over a glass of wine about delta loop antennas, we were mulling over M0PLK design and whether it was as good as everybody says. So in the spur of the slightly tipsy moment and after looking on the web at some Polish website 
I decided to buy an original M0PLK Delta Loop! The only place I could find one was at this website in Poland, well, M0PLK is polish! No other retail shop in Europe had them, Is that a good or bad sign?

£188 for the original M0PLK design, actually not a bad price, plus they have good reviews on Eham. So I'm expecting this in the New Year and I will compare notes with the homebrew to see how it performs. If its as quiet as this homebrew I shall be well impressed!

  1. Did you get a good result, especially, SWR for 20m, 17m, 15m, 12m and 10m bands? I am skeptical of the performance.
