Do some research before investing in a multiband antenna. I forget which brand it was but I was shown some photos of a 2m-440-1200 one that was taken apart after it failed.
It was just a bunch of 2m elements, and the third harmonic function worked so-so at 440, and the 9th worked a little at 1200. If you have any constructions skills then building your own specifically for 1.2GHz might be a better idea, using these articles from the antennas page at repeater-builder: <http://www.repeater-builder.com/antenna/wa6svt.html> Omni-Directional Gain Vertical Collinear Construction Project Yes, you too can build a Stationmaster - for any frequency from 2 meters to 1.3 GHz By Mike Collis WA6SVT <http://www.repeater-builder.com/antenna/uhfcoll.html> Some variations and constructions ideas on the WA6SVT collinear by Kevin Custer W3KKC <http://www.repeater-builder.com/antenna/n1bug-antenna.html> One ham's experiences with the WA6SVT antenna by Paul Kelly N1BUG <http://www.repeater-builder.com/antenna/n1bug-construction.html> Here's the construction article promised in the above article by Paul Kelly N1BUG And, BTW, they work.
