You didnt mention the wavelength and bands of interest Rod but:
- A bi-directional Beverage will show about a 3dB loss in its favored
direction compared to a terminated one. This is assuming a full wave on
160M. The loss goes up with frequency.
- F/B is usually the prime reason to install a Beverage. If you are
prepared to give up a lot of SNR then unterminated is an option. Another
choice is a 2 wire affair ( which many have extreme difficulty getting to
work properly) or feeding the single wire from both ends.
There is no free lunch on the low bands!
