    I found a post on another trucking board that details a strategy for a decent antenna setup on a Volvo. The OP hasn't posted on that site in over a year so I can't question him about it further. Since there appears to be some very knowledgeable fellas here I thought I would run the guys post by you guys and see what you thought of his "strategy" for antenna placement. Here it is....

    Thoughts??

    Yeah, I'm not buying the 60-70 mile range either... I've concluded that most people brag up the range of their radio like most men brag up the length of their %^*#! Unfortunately for me (actually make that my gf) I'm barely getting over the median right now.:biggrin_2559:

    Seriously though I'm mainly wondering about his suggestion for placement of the antenna centered on the back of the cab? Good idea or just put the antenna on a bird perch on the drivers side and be done with it? FYI, I mainly pull step deck vans or refers if it matters.

    Also I'm wondering if the Wilson Silverload will handle a Cobra 29 with the rfx75 mod?

    If your pulling deck trailers then a 102" whip is your best bang for the buck.They are about $20 at Radio Shack and work like they have always done these last 30+ years,best ears on the planet
    They'll do 1800+ watts without missing a beat :biggrin_25514:,which fwiw 40 miles aint no problem . . . . .

    When I say I pull a step deck I mean a dry van step deck like the bed buggers pull.

    I didn't know that Wilson made a 7ft antenna. I know that they make 3', 4' & 5'. I know that Skip Shooter does.

    YES the Silver Load will handle the RFX-75 and Cobra 29.

    And the 102' is the Best antenna out. It would be 1 1/2 foot longer than your 7 footer.

    Yeah, I've been unable to find a 7' wilson. I'm assuming he meant 5'. A 5' would mount to the upper grab handle (rear of the cab) and be about 2-4" above the roof. But a 7' would mount on the lower grab handle and be the same 2-4" above the roof line.

    I understand the 102 whip is the cats ### but I don't have a convenient place to mount it.

    Is a 102 whip "top loaded" like the Silveload? I'm guessing yes but I don't know. If so maybe I will find a way to mount it and make one work.

    The rear hand rail on any cab will work as long as you remember they were not designed as such and you will need to ground them to the battery is the best(when you run your ground to the frame your trusting the people that may not have grounded the handrail to ground the body and they may not have done such a hot job). Also remember that the hot portion of the antenna (above the coil) needs to be above the roof and not to close to the cab. The cab being to close will raise your SWR.

    No a 102 is not a loaded antenna. It is a 1/4 wave length not need to load it.

    Probably the best mass produced antenna for performance.

    You see poster's claim gain on antennas, they seem to forget to list what the gain is over. Most of the gain is theoretical not actual, or not gain over a 1/4 wave.

    The reasons for loading an antenna are few, 1. To be able to build a antenna that is shorter in physical length while still maintaining a decent SWR and expectable performance or 2. increasing the Bandwidth of the antenna. An example of the first would be a Wilson or Firestick, the second would be a Stryker or a Monkey Made. It is important to determine what it is your try =ing to accomplish before purchasing an antenna. If its for looks and thats what matters then you need to decide that up front.

    Will a 102 work ok behind the cab with just a few inches sticking up above the cab and trailer like the poster (quoted above) in my original post claims the Wilson Silverload will?

    If not is there a better antenna to use than the Silverload mounted in the rear of the cab with just a few inches sticking out above the roof line? FYI... I could care less about looks in any way shape or form... I'm purely after performance.
