You will probably need to submit plans from all angles and of course dimensions such as height.
Generally, flagpoles don't need planning permission, so why not camouflage it at the top of a flagpole?
You may be able to bypass the paperwork by setting it up inside the house. That includes the balcony as long as the antenna is within its railing.
Don't have a space that big Looking at 10m dipole (20m wavelength). Indoors isn't ideal...
My current though process is two small spikes on either side of the house on the vertex of the roof and then a wire between those. Should look enough like one of those snow-stoppers that it may pass unnoticed... Otherwise in the loft, but I'll get a lot less signal there
I ask as I'm also looking to put an antenna on the balcony. My balconies are on the top floor, and the roof only extends over half of the balcony. So, I could put up a fan half-wave vertical (DX Commander) but about 3m of the antenna would poke above the roof line.
I would expect that what I would like to do is not possible without the explicit permission of the building management/owner, but it would be good to get some confirmation before I go and ask for the permissions. If I ask for permissions, I'll be asking for the ability to use the roof for a temporary antenna.
Apologies if this takes the thread off-topic.
From what I can tell within my group of DX friends, no. Anything which raises the "height" of your building (even by 1cm), needs permission from the council (planning permission - not just building owner permission).
Something which can be visible from the road, in some cases, will also need permission (depends on your building).
