Total Bus Height ... How High Is Too High?
Hello Shane,
Thanks for the real-world info about height, I appreciate it. Hello John, That Galaxy DX99 is one sweet radio. Thanks for the photos, your roof looks great! I'm an old 2-way radio guy myself. Out here in the west every one is running power because we are all so far apart. Connex has a new model called the 4600 Turbo. Fully tuned it will do 205 watts on AM. Well, I just have to have one. No need for a linear, it's all in one (blue face lit) box. I want to use a Predator 10-K with it. They have a Short Whip model with a 9" shaft that stands 4' 6" high straight up. I want to put it on the foof, slightly forward of the center of the bus. Here's my problem... The K-10 is light, but the drag on the twin coil center loads is higher than you might think. I want to mount it with a Shakesphere 4187-HD stainless ratchet mount. This will still allow me to operate it while driving, from a laied back position like you do with your Wilson, and get my height down to where it needs to be. The Shakesphere mount is threaded 1" x 14. The antenna I want to use is 3/8" X 24. So I need to find an adaptor, or a different ratchet mount that would be strong enough and have the 3/8 x 24 thread. So far, I have found neither one. Shakesphere told me that they used to sell the adaptor for years, but the company that made them is no longer supplying them. Any Ideas? If I ever get this station transmitting I might be able to talk to China ...
