As a point of reference - I have 4 terminated beverages from 200 - 350m long
(also 2 unterminated bererages). I use them on 40 - 160M. I typically see
10 - 25dB of front to back on these beverages. On 40M and 80M, while
contesting, if I am not careful to first listen on the transmit antenna
before CQing, I can be on top of a US station that I can't hear because of
using the EU terminated beverage.
4db does not seem like a good result for a terminated beverage.
I can't speak to BOGs as I have not used them.
