Hi Howard,

Lucky  you :)

Here is my personal opinion from 20 years of operations--if you cannot
change polarity, don't use circular.   Linear works wonderfully.

M2 yagis work great no matter what polarity the bird is in...I have
installed mine vertically on a metal boom.  No regrets.  And they are
quite  a bit cheaper!!

My last setup purchase included three M2 yagis, and I love 'em!




Price those, and then compare the price to circular ones with polarity
switching on the 2M AND 70cm, and you'll see one reason I went that
route :)

Other reasons include quality, balance on the rotors, gain, length
(around 10'), durability, and simplicity, etc.

Add a 2' dish on a 8' to 10' horizontal metal boom and you're good for
four bands, and the standard Yaesu G5500 will do just fine with the
whole mess.

Don't get me wrong---circular is more of the ideal, but it gets a bit
more complicated with polarity switching (not easily done remotely for
example!), not to mention the expense.
