Most mobile and repeater antennas are verticle so you would want Verticle for this. Most SSB work is horizontal so you would want Horizontal for SSB.

I've got a 2m 12 element M2 yagi on the way. I can see horz for dx but how about for local repeaters as well, 30 miles away? Would it be better vert or horz?
Thanks,

I would go horizontal with the M2 and build a simple vertical for repeater work. Here are some antenna links to get some ideas, www.hamuniverse.com/2mladjpole.html
This model is very affective. Here is another link with enough projects for a life time. www.ac6v.com/antprojects.htm

I’m assuming you got the beam for SSB DX? Then leave it horizontal, even though the repeaters are vertical you will still be able to hit them cleanly. Though if you want to work FM simplex with mobiles, then you will need a vertical also.
Don’t know how much experience you have with beams, but that 12 element will have a narrower beam width then a 4 element. So an Omni antenna would compliment the station. I have a Diamond vertical for omni and the 20 element beam (10 horizontal & 10 vertical). If I only have a couple of S units on the vertical, it sometimes hard to find them on the beam, unless they give out a location.

Here's A way to do it, not the only way. www.signalengineering.com/ultimate/cubical_quad.html
There are other ways that don't involve two coax's that are more complicated. It might also work to cophase two quads and make one vertical, one horizontal. I'll have to do some research on that one...

I would think that thre's a way that hasn't been suggested yet. Try mounting the beam horizontally and hitting the repeaters. If that's possible, then there's not really a problem, is there?

PS - If I missed a post with this suggestion already in it, I have a good excuse. I just finished my taxes... I don't want to talk about it either!

Thanks for the reply's.
That's what I was wondering, I should've worded my question more precise. I wasn't sure on FM if you would get that warbly sound when using horz locally like you do with ssb for local use when others are running vert.
I looked at the CP models, but wasn't sure how circular did for local. Since those were more for eme design. I really want to be able to get the longer repeaters as well, lets say up to the 200mile range. I had about decided to go ahead and mount in horz and if I get problem with the local repeaters and local simplex, I'll stick a smaller vert up there as well for shorter range. I was trying to get one that would let me get some good out of local and dx without running muliple coax lines for each. ( I know, don't laugh) <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT="
">
Since the beam is so tight, I was seriously thinking of one of those M2 HO loops for listening. They're small, and I'm guessing I could mount this above the beam?
Thanks again.
Hey Doc, tax wise, I'll trade you. <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/roll.gif ALT=":rollin">

They can be found cheap at swap meets or on E-Bay like this one... Transco <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/wink.gif ALT="">
