HOA says no external antenna... Looking for advice

[222DBFL]

You could try what some do in their attic, which is use 2 x 5ft firestick antennas and a build a mount out of large metal strapping with the holes in it. You can make an inverted V or place them horizontally. Here are a couple photos of ones. Something like this, but make it an inverted V if you like. The 2 that are pictured appear to be setup more for local and DX use rather than being horizontal for mostly DX use. Horizontally mounted, your local distance might not be that great. 5 miles maybe a little more maybe less. I've a dipole about 40ft up or more and it works for about 8 miles. And that is it. That is a horizontal one. But for DX it's great and the noise levels are normally lower.
Anyways. You can make yourself a bracket or hit the local truck stop if you have one or online, and get a couple mirror mounts and try those as well for making one in the attic. But I've heard many say that this setup does work for what it is. Hope this helps and have a good one.
