The Force12 page give an analysis and loosely claims 16dB improvement
over the unloaded antenna, but that is probably based on ignoring ground
resistance again.


Force 12 advertising has been ignoring the laws of physics since they
first went into business and started their fantasy gain baloney...
Now, that is not to take away from Tom's innovative approach to beam
design and beam construction... He has done some nice things...
