Based on a 7m telescopic pole (circa 6.8m) and will work from 40m through to 2m band. Incredible.
Cut Chart as follows. Cut your elements this long (in metres – not feet : )
30m 7.99 (includes 2 x 6cm loops and a 1.29m return off the top)
20m 4.95 (all these have a 6cm loop incorporated into this cut chart)
To clarify: Taking the 10m band for instance, cut your element at 2.50m exactly and fold-back a loop of 6cm which makes the new total length of 2.44m.
Want feet and inches? Just Google “convert 2.81m to feet and inches” (for instance).
MMANA 2 Element Delta Loop modelling: I mentioned this on Saturday’s LiveStream. You can download it and have a play, rotate it, delete the reflector etc:

Fan dipoles are the easiest multi-band antenna you may wish to have a go at.
You can buy an expensive switch box to accomplish phased array system. But to test out the theory if you’d like to go down this route, you could try a simple vertical yagi?
Check out my film and decide for yourself.
There are benefits to both. Height above ground will kill a vertical. But do you have the height?
Some people aren’t quite sure how easy it is to build a mono-band quarter wave. They are cheap and extremely easy to build.
Check out the video.
Surprise surprise. I was astonished that a cobweb isn’t as bad as I thought it was, certainly in software modelling.
Check it out.
A G5RV is really a doublet, using the feedline to transform (automagically) some pretty nasty impedances to a suitable impedance for coax.
I explain this here:
An inverted L is just like a vertical apart from the fact that instead of going straight up (like a tuned quarter-wave), it turns 90 degrees somewhere.
I discuss this in this video:
I cover this in my youtube video. CHeck it out.
Here’s the spreadsheet:

In this video, I show you why you shouldn’t worry about height for your wire dipoles and loops.
Unless you can achieve leaps of a quarter-wave in size, just go with the flow (or put up a DX Commander All-Band-Vertical!
Compare Red 5/8th -vs- Blue W/wave
Anyone who has mucked about with verticals will no doubt have worked out that a full-sized quarter-wave for the 40m band, more or less tunes up for 15m band.
It wasn’t until my entry in IOTA Contest this year that I convinced myself that they are not a cloudburner (as many people suggest) but compare favorably with a quarter-wave, even producing more gain by 2 dB at 10 degrees above the horizon.
OK, so 2 dB isn’t a huge gain, but hey – it’s free. Take it when you can!
Don’t forget, you can do the same for 10m band too by making an element 6.83m long and folding it back a further 1.11m (for 28.5 MHz). So you’ll need nearly 8m of wire. Don’t forget, that’s insulated wire!
