Commercial/professional antennas typically have real measured gain but CB companies and most foreign antenna mfrs calculate and stretch the truth or simply make up numbers that sell. Midland has been doing this since the 1970s. There are two gain standards that are different by 2.14dB and either...

The Comet CA-2X4SRNMO works well and covers 2m amateur, commercial VHF, 70cm amateur and GMRS but a dedicated UHF antenna like the Laird B4505 works a little better On GMRS. I have several of each and swap them around with a dozen other antennas when I get bored.

Looking at the size of the Highland antenna I would estimate its gain in the 4dBd range, it’s not possible to have 6.6dBd gain in a roughly 4ft tall antenna. That takes about 7ft in a vertical stacked collinear array which is what’s under the plastic radome. Also, the short stubby ghost antennas...

I guess you would be ok at an off road event where you had to pay for a $50 USFS off-road user permit and I whizz by you with no off-road permit or drivers license.

We all know the JT is a bit low on radio mounting space while being able to see the radio display and not give up something else. I've had a number of radios in my 21 Mojave and up to now have settled on three operating at the same time. An old Icom 706MK2G for HF and secondary for 2m/440...

Oh, ahhhhh, I see now. Disregard….

A stock AM/FM antenna is typically a tuned 1/4 wave whip for the 88-108MHz FM band and it operates as a very high impedance E field probe for the .55 to 1.6MHz AM band. An AM/FM car radio has an antenna matching circuit to make the stock FM band tuned antenna work on the AM band. If you...

Many if not most people mount the ghost antenna on a bracket that sticks out between the front fender and hood at the side of the cowl placing the antenna nearly 6" below hood line. That will severally distort the radiation pattern and there is no ground plane under the antenna and all of that...

Most of the entire upper part of a Gladiator is fiberglass and transparent to RF except for the thin steel A pillars and top windshield frame, but the windshield opening is very large in wavelength at UHF and not a problem. A hood mounted UHF antenna works very well on a Gladiator, I've done...

No, that would be reserved for the "Jellystone Park" edition. I spend a lot of time in Big Bear, CA and see more Jeep Gladiators there than anywhere else. I constantly get honked and waved at by other Gladiators and I also see an unusually high number of Telsa trucks and also Rivian trucks...

If the antenna was tuned on the smaller plate then it may be off a bit with more ground plane. Its hard to comment without seeing the setup.

Many trunk lip mounts will fit the hood and no holes needed, there are two setscrews on the underside of the hood lip that holds it on. This places the antenna on top of the hood with a good ground plane. I also removed the plastic side cowl piece that curves down and lined it with 3" wide...

What kind of range are you looking for, close in trail use or longer range down a hwy or to repeaters? For longer range you might consider a trunk lip mount on top of the hood near the hinges and either a 15" tall UHF 1/2 wave or stacked 5/8 over 5/8 wave for GMRS or for dual band VHF/UHF...

Yup, If you don't have some really strong stations in your town you will loose some stations. You can do a basic test before you buy a short antenna by logging what you can hear on both AM and FM then remove the stock antenna and clip on 13" of wire and see what happens. If you have equipment...

FM band is a little less effected by moderate changes in antenna length, I get reasonable FM reception with my 13" version on FM and I go through automatic car washes all the time. Here is the antenna I got and you can't believe any advertising claims, they are all lies. They claim "The material...

I tested a few and there is a huge reduction in reception. You can't tell on local super strong stations but if you tune in a few marginal to weak AM stations on the stock antenna then swap to a tiny one they go away. I settled on a 13" tall job that works good enough on my two 50,000 watt local...

I have a Yaesu FTM-400DR, Icom 706MKIIG and a Harris XG-100M in my JT. The Yaesu is dual band, Icom is HF through 70cm and the Harris is 30-870MHz. I can monitor four freqs simultaneously if needed and drive the wifee insane.

I would avoid the Yaesu FT-857, they worked ok in their day but its a pretty old radio now. If you just want 2m/70cm on amateur plus GMRS and are willing to break some rules the FTM-500 will work well for both services and its nice having a single radio do it all with the limited space in the...

The Starlink antenna is an electronically steered array that would radiate mostly upwards from the antenna, very little RF off the sides or back. At Ku band any danger would be close range to your eyes like looking right into the front of the antenna. RF at Ku band will not penetrate the body...

Those wire size vs current ranges are more for wire heating inside conduit to met the NEC. For vehicle use with a long run I also think 8ga is a good size to start with and I usually upsize to reduce voltage drop since you will usually add more power hungry things in the future. For a 15ft run...
