[TowerTalk] OptiBeam OBDYA12-5 and NN4ZZ TiltPlate

[William Greaves]

Art,I'm in the process of assembling this Optibeam and can send you the manual, but I'm away from the paper manual for a couple of weeks. I'm also interested in NN4ZZ tiltplate for this Optibeam.Bill K9GN

I want to mount it on an existing NN4ZZ TiltPlate.The old NN4ZZ site shows an adapter for the OptiBeam square booms. In this case, the boom is 40mm square and a 2.5-inch OD aluminum tube is used as an adapter. That's all good. I can fabricate the adapter or puchase it pre-made if it is available from Degen Designs.But I have questions about this particular antenna. Will the adapter clear the phasing lines that run under the boom sufficiently? Does the element spacing around the nominal center of the boom allow for the 18-inch TiltPlate? Will the elements nearest the mast clear the tower as it is tilted over?OptiBeam does not make the antenna manual available without purchase, and dimensional information that would answer my questions is not available from OptiBeam (I did ask).Does anyone here have this antenna and can provide the dimensions that I need? Even better, has anyone attempted to mount this antenna to a TiltPlate?Thanks.-- Art GreenbergWA2LLNart at artg.tv______________________________________________________________________________________________TowerTalk mailing listTowerTalk at contesting.comhttp://lists.contesting.com/mailman/listinfo/towertalk
