Default Stacking beams

I have a Tennamast rotator cage. I want to install a Cushcraft MA5B beam at
the bottom and a 9 element crossed Tonna beam for 2 meters with a 2m
collinear on top of that.

What should the minimum distance be from the rotator cage to the MA5B?

What should the minimum distance be from the MA5B and the 9 element crossed
Tonna?

What should the minimum distance be from the 9 element Tonna to the 2 meter
collinear?

Thanks

Andy

Default Stacking beams

What I should of asked is, what is the minimum spacing I can get away with,
without the antenna's effecting each other or the rotator cage effecting the
MA5B?

Thanks

Stacking 20 meter beams at 100 and 200 feet is good.

I can only get my upper one to 193.
Do you think I should use a hamstick instead?

Andy,
The best distance between stacked beams is the most you can get and
stay sort of practical. If the mast between beams is too long then
it's going to bend, which is bad. If too short, then those beams
might as well be all on the same boom. And until the distance between
them gets really ridiculous, they are going to affect each other no
matter what you do. So, I guess it depends on what you can manage.
There are probably as many 'rules of thumb's as there are thumbs
putting up stacked antennas, so, pick one you can live with.

Above the rotator cage. NOT FROM THE GROUND!

Doc, thank you for your reply.

I guess its a case of trying different spacing and see what works best. The
closer I can get them together the happier the neighbours will be.
Hopefully.
