[BVARC] HF Antenna Advice

[Karl Bernard]

David,

I wouldn't think that a dipole of any kind would put too much of a strain
on your chimney. 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.

Thanks,

Karl
