HF mobile ant HELP!! Frustrated!!

[W9JCM]

I am using or trying to use a 4 mag mount setup with a diamond hv7 ant. its
good on 2 but hf sucks. also,, i get the mount and it has a so-239 on it and
then a wire soldered and i am supposed to hook it up to the a dam 3/8-24.. what the hell is that??? where is my
uhf type mount.. so i soldered a 1 foot chunck of belden to the so239
screwed the ant on it and hooked up my coax.  I think i am going to just
order a comet lip mount with a uhf assembly or should i get the uhf assembly
and drill a hole for it in the mag mount setup and try it that way.. any
ideas guys?

Yes the Diamond models have an so239 end. You will need an pl259 mount such as that from Comet...I believe it is mount model RS-731. The reason that HF probably does not work well probably deals eith the mag mount you are trying to use. The antenna needs a good ground to the body/frame. Im not sure a mag-mount will do this. Even if you are grounded to the roof or trunk...that body part must in turn be grounded to the frame eventually. I have the MV3A, similar to HV7 and have had great signals without any problem on any bands...but I am not using a mag-mount. Good luck and hope this helps. You may try contacting Diamond for further help. DA1TJO/N0TJO

Everyone has different situations but my suggestion is to get rid of the mag mount all together.  Put on a decent mount that will give you a good ground and support...if you are worried about damaging your vehicle the mag mount will do far more harm than just putting in a good antenna system.  KB9UMT  Don

First, what kind of vehicle do you have??? Second, why a mag mount for hf anyway?? Give us more information so we can help you!!! You can make anything as long as you keep an open mind. If you have a pick-up, you have several options available. If you have a car, you still have some options to work with. Trailer hitches make excellent antenna supports. They make mounts that go in your truck beds stake pocket. NO HOLES REQUIRED!!! On a car, MFJ makes a lip mount that will work on your trunk lid or a rear hatch of a mini van or SUV. Get the picture?
