There is no big difference between Navassa5 and Optibeam9-5 antennas in
gain. On the other hand Navassa5 has almost 5 feet shorter boom and extra
element (ten total). First version of Navassa5 had a foot longer boom and
was produced and sold by me in Europe as MY5T antenna since 2010. It had T
loading on 20m elements for smaller look and had similar gain and F/B as
Navassa5.
Navassa 5 has excellent mechanical design thanks to JKantennas with whom I
have business arrangements (disclosure) as well as electrical design thanks
to both of our companies.
Some pictures and data of MY5T are here http://myantennas.com/wp/news/
as well as Manual in metric sizes here
