I use a moxon here for 10,15 and 20m with a inverted V for 17m sitting over the frame. It uses wire rather than aluminium elements, plenty of stuff online for dimensions and build ideas and it is a fairly mini (ie has no traps but the element ends fold in).

ill take a look at the the moxon, thank you,

I was leaning towards a some form of mini beam I know these arnt to big, but thought the mini beam has less impact in the air

the mrs has said ok to a beam but I have said it isn't to big lol

and the only beam she knows of is a tv antenna lol

I have shown her some pics lol

A 20m beam is big but at 24 ft span a moxon is not as bad as it could be.....and it has not traps. You could start at 10/15 and grow it over the winter in the dark nights?

If you have a look on my QRZ.com page at the bottom you can see a photo my 2 bed ex council semi and how a 20m Moxon looks on the side if it. My Mrs is mega fussy with antennas but she tolerates it.....it only really got noticed when she was sitting out in the garden this summer so with the UK weather that won't be an ongoing problem.

If you want some build notes drop me a PM of your email address and I will send over some stuff for you to have a look at I wrote out for someone else.

The moxon was originally based on the VK2ABQbeam. 15ft by 15ft sq for 10/15/20 but slightly worse f/b and other stuff that Steve could tell us about. The Moxon is an improved design of the VK2ABQ but has a wider span as result.

I guess it all depends what you think the XYL would find acceptable!

A hexbeam would have a smaller turn radius than the Moxon, but some folk are put off by its shape. However a monobander doesn't need any height, so it might look more acceptable. To give you some idea what it would look like, here's an experimental monobander I had at one stage:

Tell the XYL it's a capacity hat for top loading your vertical!

lol good idea steve

that looks like a good idea, although I have had a cobweb up before and she was not impressed lol and this design would be the same to her I think but thanks for the input, I am thinking of trying the moxon for starters, 20m mono band one, then as she gets used to it I will add other bands or simply grow it through the winter ;)

what kind of height would you suggest ?

I was thinking 40ft, I have roast potatoe (rotor) so that's all okay and everything else to erect it, just got to make a final decision on what im doing

thanks in advance

:P

In my experience, the higher you can get any beam the less objectionable it looks; anything over 100ft and she wont even notice it ;)

Agreed. My hexbeam looked massive on the floor when building it to the point I wondered if it was going to fit but 40ft up it looks a lot smaller.

What band was that Hex for Steve as that might sneak past the neighbours especially is it's on my gable rather than at the end of the garden... it has to be 10 though I guess rather than 17? :blackeye:

Cheers, Dave.

Dave,

Yes - that was a 10m version. I showed it to illustrate what a "flat" monobander looks like. It's up about 15ft in that photo, so a 20m version would look similar at 30ft.
