Saw the great reviews on eham.net so I got one off of ebay for $79
It works ok, and does tune up on all the bands 40m-6m.
It uses a dummy load similar to the Diamond BB7V verticals as described in: http://g8jnj.webs.com/cometcha250b.htm
Here it is horizontal:
And vertical with a fiberglass pole:
I took it home a tried using a Mr. Longarm from homedepot so it can be used as a sloper
I wanted to compare the ultimax 100 to a 20m dipole so I did this setup. The 20m dipole was almost 2 S-units above the ultimax 100, which is to be expected.
