But you didn't compare the difference in signal quality mounted on a ground plane vs high above it. You will notice that.

You'll probably find the VSWR is high because the base of the antenna needs to be sitting on an adequate amount of ground plane to both give a low VSWR and also radiate and perform. Raising the antenna above a ground plane more than a fraction of an inch will cause all sorts of problems and this...

Is this all stated by Jeep or is it a theory? I don't know the facts about IBS but I believe the IBS does not "count" how much current goes out vs in and instead when you start the vehicle it comes alive and measures battery voltage and charge current to know the approximate battery state of...

How old is the battery and its it stock or replacement? I've run across old batteries in solar systems where the electrolyte was very low and would not take much of a charge and the charger voltage ended up very high like you are seeing. Along with the other suggestions I would do a battery...

I recently removed my aux battery and pulled F42. Now I'm looking at a group 94R Odyssey for the main battery and would like to know if anyone has used one for say 4-5yrs and had a good or bad experience?

Did you happen to work with Rich Fusinski at GM?

The Way of life and Quake don't offer very much ground plane as mounted in the pictures which can make it difficult to get a good match and performance (distance) will suffer. I found various mounts on the inside upper bed wall use the vertical bed wall and basically the entire bed area as a...

If your looking at a thick fiberglass antenna like a Firestick over about 3ft tall vibration over time will have its way with a single bolt mount. On a good trunk lip mount from Laird or other high end commercial mfr the metal bracket that wraps around under the hood with two set screws is...

Not sure I would trust a mount that has only one hole to bolt it down. Have you considered a base loaded whip like the Larsen NMO27 or similar versions from Tram/Browning? You could then use an NMO trunk lip mount on the hood near the hinges which works well.

Laird/TE connectivity B4502 is a 12.5" tall 1/2 wave with NMO mount, works great for its size and better than a 1/4 wave for GMRS. You can get them used in perfect shape cheap on fleabay. The Comet SS-680SBNMO is a 2m/70cm with a little gain and happens to be 27" tall.

Many GMRS users run Motorola or Harris or other commercial radios which can do MCD1200 signaling, which is left over technology from police/public service analog radio systems. You might hear this as a quick bleepity bleep bleep at the end of a transmission and the unit # will be displayed on...

On digital systems like P25, DMR, etc, there is a unit ID# sent with each transmission and that is assigned by the system operator. Some radios are set up to read user IDs some are not but the system operator can read them all. The ID is sent as digital data and not heard by users.

Hummer antenna brackets are on eBay and here is one. https://www.ebay.com/itm/185308844230 Most Military/HMMWV antennas you see on eBay are about 9ft tall and cover roughly 30 to 90MHz and you need one that covers 462-467MHz. Most look the same as the 30-90MHz version but can cover 30-512MHz...

If your need is just for spotting and short range like less than 1/2 mi outdoors, handhelds should work fine.

I purchased mine about 4yrs ago for my 21 Mojave. I think they were a little less back then but figuring in my labor rate actually cheaper than making one.

The install looks great but why didn’t you just get the BadgeGlow Aux Board barrier strip? It’s made for exactly what you are doing and it’s nicely labeled. This picture was poached off the Jeep Wrangler forum and shows a BadgeGlow with winch relay.

I don’t think either link is water tight. Consider anything on the floor pan subject to being completely submerged under water. Insulated cables are ok but I would avoid any exposed connections under the vehicle. You might consider running cables up under the rear seats then distribute from...

Yea, a camper or bed rack really screws with that inside bed wall antenna mounting. I attached my HMMVW mount with six PEM nuts into the bed wall and it’s not going anywhere. I was so happy with this flexible antenna mount and then I got a bed rack which screwed placing any antennas on the...

Yes, you basically have a small UHF base antenna on a spring which can have some performance advantages and mounting disadvantages. I have a HMMVW mount on my Mojave inside bed wall behind a wheel well and use adaptor plates for various military and commercial antennas, HF through UHF.

If you go here and scroll down to the colorful lineup of antenna models, the Highlander would be basically like an MXTA26 whip with a 1/4 wave decoupling stub at the base to try and isolate it from the coax, then stuffed inside a plastic or fiberglass pipe. The entire length of the plastic pipe...
