In looking at the original message in this thread, I have used the absolutely most simple solution that is likely available anywhere. I am using a Syntor X9000 on both 10 and 6 M without anymore than a cut for 6M mobile "bird killer" whip and its associated spring with a Hustler 10M coil on top. Rounding up the necessary fittings for the top might take some looking but I have found them at least at the vendors at Dayton. The mount that I am using on one car is a homemade bracket that fastens between the fender and the hood and has an SO239 on one end and a 3/8 x 24 thread going at 90 degrees. It works perfectly. In fact I have two of them in use on two different vehicles.
Simply cut the whip for probably 52.5 or so and establish the lowest SWR with the 10M coil attached and then adjust the 10M coil for resonance on 29.6. Other than the coil getting smacked once in awhile coming to near destruction I have had little problem with this set up. In probably about 5 years with this set up I've only lost one coil. Just one tech's / ham's idea/opinion. Now if the bands would only open up a little bit. HI! Thanks Steve Waltman KB3FPN
