Ron,
I have an M2 23CM35EZ which works very well with AO-51. Overkill on AO-51, and probably marginal for P3, though they are easy to stack for gain. http://www.m2inc.com/products/uhf/23cm/23cm35ez.html
If you want to go with a commercial helix, Directive Systems makes the DSH23-12. A friend bought one, and in fact got them to make one with a few more turns in it. It worked well, and is certainly designed to withstand the elements. http://www.directivesystems.com/new.htm
