Hello Cecil,

If you are willing to do a little homebrewing, you can construct as good an 
antenna (or better) than anything commercially available:

You can make the antennas as rugged as is required by your local weather.  For 
detailed example of how one person constructed his YU7EF yagi:

I have worked a number of YU7EF yagis on 6m EME, and they really work.  I will 
add, though, that I have noticed a significant reduction in ground gain when 6m 
beams are mounted above HF beams, which tend to look like ground and shield the 6m 
beams from precious reflections coming up from the ground.  However, if you are 
aren't looking for the extra dB of ground gain and are happy with an all-round 
beam for casual use, that type of installation probably will satisfy your needs.

GL and VY 73, Lance
