Bruce I have assumed I would need automatic tracking for satellite work. Are there limitations to a fixed angle antenna, and is fixed the norm?Mark N5PRD

Never actually heard of any myself. Is it about it not being sturdy or something else?

Even went though several high wind events. One removed a large portion of the roof.

Even with the balun, that one only weighs 1.2lb (per DX Engineering - https://www.dxengineering.com/parts/mfj-2010). Since whatever you use as a mount will weigh more than the antenna, just be sure to use a lightweight mount. Disclaimer - this only my opinion. I've never mounted an antenna on a chimney before.

I have also passed both my General and Extra exam about a month ago. I am working on setting up a HF radio for home. I have a ‘backordered’ IC-7300 which may show up one day. In the mean time, I am trying to plan for my HF antenna that will fit on my small lot. I think I can run an 40-20-10-6 OCFD (*MFJ-2010) in a slope from a tree in my front yard, with the feed point hung off a mounted on chimney, and then on to a post above my fence in my backyard. I don’t have any trees in my backyard. Instead I have power lines across the back of the lot that I have to avoid. I keep reading various comments and warnings about using a chimney for a mount. My chimney is in good repair, having been inspected and repaired during my home rebuilt after being flooded during Harvey. Is the center of the OCFD a light enough load to consider using my chimney as a center mount? Is there a right way to do that? Or should I ‘bite the bullet’ and setup a pole beside the chimney? Any other antenna advice for a novice?
