I like my DXLOOP .. an interesting project with a higher gain compared to Alexloop .... i use 1,2m external diameter with Cellflex 1/2" (copper ext. diam 12,3mm) .. AlexLoop use 1m with RS217 (cooper ext diam7,35mm) ... the theoretical gains are higher (20m DXLOOP efficiency than the dipole positioned half-wave height: 66% -- 20m ALEXLOOP efficiency: 37,8%), (40m DXLOOP efficiency: 15,1% -- 20m ALEXLOOP efficiency: 5,1%) .... You can see my project  http://www.qsl.net/ik5xct/   lookat DXLOOP  or watch this video https://youtu.be/quADHsJWWjA ... Anyway .. Alexloop is a good product but very expensive !!!

My favorite is the Par Endfedz 10-20-40 with my 31 foot jacktite fiberglass telescoping pole. I am setup in just minutes. When I feel like struggling a little, I use my buddiepole antenna. I like it, but just takes too long too setup.

Enjoying this discussion of portable antennas. Last
summer obtained a telescoping mast from spiderbeam.
All manner of longwires, loops etc. strung up quickly
and easily.

I've also got a Spiderbeam pole and use it to support a 20/30m trapped GP when we go the island of Barra in the Outer Hebrides. It's a VERY windy location so have to ensure the pole is well guyed!

Greetings Dave ! Having my morning coffee and viewing
your excellent photography at:
https://dxnews.com/gm0lvi-p/
 Any advice on how you guy your mast under such
windy conditions ? When I purchased my mast
the folks at spiderbeam had this webbing
sewn in a unique shape for attaching guy lines.
I've yet to try it.

I guy the mast at the 7m height and also lower down a few metres above the base. The radials which are made from fairly strong wire also prove a little support, though I try not to put much stress on them.
I did get that fabric guy ring from Spiderbeams but wasn't terribly pleased with it and now use a pair of plastics guy rings from Sota beams - these are slightly tapered on the inside and form a very snug fit on the pole.
