    Tips I wish the real radio geeks would have told me when I first started:
    • Drill a hole through the dead center of the roof with this and run a real NMO mount from either Laird or Larsen to your unit. Take the plunge. Commit!
    • The mount should be factory-connected via a flexible RG58A/U (A/U type simply means a 20 AWG stranded tinned copper center conductor wire).
    • Mag, hood bracket, and bed mounts are good for temporary-ish comms, but can't even come close to comparing to the range and clarity of a proper roof install.
    • Keep a plastic NMO rain cap handy for when you need to quickly remove the antenna.
    • Use the best possible metal-shielded RJ45 female/female connector you can find. Anything less is subject to plenty of interference, which is so annoying after you buy all and install the supplies and then realize it's crap like I did. :facepalm:
    • Mount the shielded RJ45 connector into the Toyota switch blank of your choice.
      • Caveat Emptor: the Australian company GearElectric makes one of these for Toyota and it has terrible craftsmanship with loose-fitting tolerances, poor 3D printing, and outrageously expensive.
    • Lastly, DPD Productions has the ugliest website and if I had time I'd offer to rebuild it, but they really know their stuff as well as the expected radioreference.com and Antenna Farm.
    If anyone else has more tips, please add for the benefit of the Tacommunity...

    Question for ya then: I have a prinsu rack with a solar panel/other shit bolted on to my roof. Do you think drilling a hole into my roof is still the best bet? I am not being difficult -- I figured the additional metal around the antenna would affect reception decently. Otherwise my plan was to mount my antenna to my roof rack.

    I just installed my cobra 75 wx st but when I turned on the unit the lights came on but nothing showed in the display window. anybody have any idea how I screwed this up? Would the antenna ground cause this?

    Instead of those NMO hole saws use a 3/4 Greenlee “CHASSIS” punch. It makes an extremely clean hole like it was from factory.

    They are pricey brand new but can be found cheap on eBay.

    If nothing is showing up on the display it sounds like something is wrong with the radio itself. Even if you don’t have an antenna hooked up to it, it should still display channels and stuff.

    Be really careful using a punch. There is a punch out there labeled 3/4", but it's actually a bit larger then 3/4". It's designed for 3/4" conduit. So measure that punch before you make that hole!!

    That’s why I capitalized “Chassis”. Conduit punches will put a larger hole than intended.

    This one is over my head. I have no idea. I would ask smart HAM guys. There are so many ways to do things where it works well, but only one way it works best for each unique situation.

    Probably not. Attach to the rack. Furnish a photo for us to be certain.

    Of the finished install? I can do that. Just ordering a new antenna and I'll be all set.

    Ok I could use some SWR help. Today I installed my Cobra C75WXST using this writeup as a guide. I've got a 4' Firestick mounted to a @RelentlessFabrication ditch light bracket. I spray painted it, and to ground it I used a 10 gauge wire and ran it to my negative terminal bus bar. I cannot shorten the adjustment enough and my SWR is always too high. On channel 1 its about 2.25 and on channel 40 its about 3.5. If I remove the spring and quick disconnect (making the whole antenna system shorter), the numbers do get slightly better but still aways above 3 on channel 40.

    Tonight I bought a ground strap that I will replace the wire with. Where exactly should it be sandwiched between the other components? Is there a better location to attach the other end to? I also realize now that I should have tested with the door closed. I did not. I will try that tomorrow. See my pictures for how I have it setup now.

    I was able to communicate clearly with someone about 15 miles away from atop a hill in my neighborhood that looks out for miles, which was a great confidence boost. But I know that I could damage components if I don't get my SWR in line.

    Would a 3' antenna work better since it is technically shorter?

    speaker and tweater upgrade DMM phone mount and a large wishlist
    So, just installed my Kenwood D710G in the truck today. Ill post some pictures when my phone charges. I installed the brick under the driver seat, speaker is just forward on the side near the hand brake. Im waiting on a blank switch for the mic to install that so my mic will plug into the lower switch section when in use. I also am running a 1/4 wave NMO antenna with the victory 4x4 hood mount. Now looking into ways to mount the head unit onto my DMM. i think i may just use another ram mount and small phone holder. and then run the RJ45 cable behind the my stereo display then ill knotch out a section of the trim on top and run it next to the head unit so that its mostly hidden and if i dont have the head unit installed i can shove the wire back down so only the connector is seen. But i have to figure out why i am getting such high reflected power. Im getting 20w forward and 10w reflected. No bueno...

    I think your ground is wrong, should be on the bottom between the bottom nut and the mount

    I think you’re right. Found this picture while researching online shows the same thing you said. Will try tomorrow morning.

    I'm glad you found your issue:thumbsup:. Now the actual ground ground doesn't have to be connected right to the antenna. You could ground your bracket, and then just make sure there is proper contact bracket and the exterior part of the stud ("G" on that picture). If not, just make sure that ground ring doesn't touch the actual stud ("H"). Also, it would be better to keep your ground wire short, and ground it to the fender, instead of the battery.

    I marked in red where you could attach that ground strap, just like mentioned before, make sure it doesn't touch the actual stud! And as mentioned above, shortter ground is better, find a spot on a fender.

    Also, I don't think there is a need for you to change the antenna.

    Good luck! And please report back after you correct it.
