Is anybody can point to good 80&40m areal design link (or 160/80/40). Double banded inv v or similar.

The GM0ONX inverted 'L' is hard to beat for limited space, and the gentleman himself is on here.

G5RV or 80m/40m trapped dipole are other options - probably better suited to Inter-G/Europe contacts.

Ho Steve, thank you for replay. What about feed two individual dipoles via one coax. Wires separate with spacers?

Yep, dipoles are much better for high-angle, but a dipole for 80m is a big beastie.

My Brother-in-Law in Canada is getting great results from an inverted V doublet, cut for a half-wave at about 5.5 MHz - i.e. half-way between 80m and 40m - and fed with open wire twin straight into a balanced ATU.

He's another one praying to the five megs fairy too.

I thought you said 'for a typical garden'.

If you can pull a 130-odd foot 80m dipole across it, that's not a typical garden :)

Well ... Slightly less then that :) or need to bend the dipole to make L shape on both sides:) not sure how will it be if exces bent along side of fence :)?

It doesn't really matter what you do to the 'outer third' of a dipole. As you know the 'work' is all done by the middle.

Just try to have both ends about the same height above ground, and Bob's your uncle.

I think will try with double band dipole feeder from the same coax and bent the what is will not fit ...
Anyway...really big thank you to all who replied.

With best regards, Kes.

You're very welcome.
Twin dipole is fine, just splay the ends of the 40m dipole away at an angle from the 80m one.

I like the 'swastika' shape, in other words the dipole ends bent in different directions. Sort of a 'Z' shape. I don't know how well it shapes up on Eznec etc, or whether it actually makes any difference, but it's worked for me up in the loft :)

Don't forget Steve, of course.

I can only give the 'ballpark' answer, but if it doesn't work, he will tell you EXACTLY why, and how to fix it.
