I finally got my vertical up, Hustler 5BTV, the antenna is obove my shop with a metal roof, Roof dimensions are 32X31 feet. I wasn't sure what dimension chart to use for the assembly from DX engineering, so I Used the mounted on roof with radials. but there are dimensions also for tower with radials, ground no radials, ground with radials. I used the prefered radial for metal roof instuctions with 16 radials draped over the metal roof. I didn't connect the antenna gnd feed point to the roof ( wasn't sure if I was supposed to ) Is there any best method for this installation on a metal roof? Any idea what dimension chart I should use? I was thinking about reseting it to the ground mount with radial settings as my radials are not tuned length just random length. Also the radials are all the same length with some of them hanging off the edge of the roof. I was able to get 10m to tune but 15 is way off it's lowest swr is 2.0 at 19.8-- mhz, Have a antenna analyzer to tune with (MFJ 259b) the other 20 and 40 are about the same and 80 I have a dip at 1.4 swr at 3.7815 Not sure what I'm doing wrong here or what I should change on the setup.
