The set screws poking through paint on a trunk lid or hood is fine as long as they are making electrical contact. That allows the RF currents to flow from the antenna grounding point to the ground plane and back, etc. I have two of those mounts on my hood. An antenna ground is not the same as a...

Midland is a radio company and I've had a few friends that worked for them years ago designing radios. They are not an antenna company and their marketing dept simply orders and rebrands other antennas. Their rebranded 6dB advertised antenna is actually around 2dBd gain. The little pud antenna...

I don't think anyone said it wouldn't work but antenna people will tell you it won't work very well compared to being mounted on a proper ground plane. When you raise an antenna like this off the ground plane you introduce loss and usually a big change in impedance. It will certainly talk down...

It was taking a couple of days for a license to get issued last few I did but it will come.

It probably won't get fixed. I would recommend doing it again, following all instructions and if they recommend using a certain browser, do that too. Then you should get a link to the payment site and after you make payment you are good. I sort of remember renewing a license not long ago and...

Is this for GMRS? You fill out the form online and when you submit it should take you to a payment site right away. There is nothing for them to approve except for they got your $$. If you didn't make a payment its probably lost in limbo somewhere.

That should be fine for 1/4 wave whips. If you plan on upgrading to a larger UHF antenna later you might consider the 19" and 6" spacings from the edge giving a little more space between antennas.

The reason I asked about antenna types is a small 6" 1/4 wave whip for GMRS will go unnoticed close to the 2m antenna. If the GMRS antenna is a larger stacked 5/8 over 5/8 colinear then it will affect the radiation pattern of the 2m antenna if its within about 6ft or less. If a GMRS antenna is...

No difference in performance with or without perforations as you describe for a 2m or GMRS ground plane. The size you mention should work great, way more than adequate for both bands. Its best if you mount the GMRS antenna with at least 6" to the edge and the 2m at least 19" to the edge of the...

Looks very good overall. The CB SWR readings show more than likely the whip is a bit too long. If there is enough whip below the set screw where you could trim off another 1/2" or so it should be safe to do so. But if nothing changes its really fine, nothing to worry about. A 1.5:1 or less SWR...

The video says "if you have the Alpine premium audio system upgrade this will not fit". I have that. Bummer dude.

Yes, tuning with a reference mic in the drivers seat or having a DSP auto EQ unit can make a huge difference. You don't really know what you have without trained ears and a reference mic and audio spectrum analyzer listening while playing pink noise through the system will reveal a lot.

I think the ultimate success here will come from a dealer and installer who has specific experience with the Gladiator who has found the right combination of equipment and who has the ears to actually know they have arrived. There has been some good information posted in the Jeep forums on...

Using the full 20" mast below the coil will put out a measurably better signal than using a 10" mast. It may only be a dB or so and a fraction of an S unit on the receive end, but a single S unit is supposed to be a 6dB change in signal level. If they give you the option to use one or both masts...

On a center loaded antenna most of the radiation off the antenna is below the coil. I know this doesn't make sense to some but that's how it works. A base loaded antenna with the coil right at the feedpoint will have more loss compared to a center or top load with everything else being equal...

You can legally program all GMRS and FRS channels as narrow band and the only issue will be lower/softer sounding transmit audio on the channels where wide band is used. Midland radios that are narrow band only would obviously be legal but their marketing and engineering people did make a...

All GMRS channels are wide band 5KHz deviation as well as FRS ch 1-8 in the 462MHz range. FRS ch 9-14 are narrow band 2.5KHz deviation in the 467MHz range.

Need is just a word. If you want it, just get it! I have a garage full of radios I don't need. But I really want them.

The info at post #17 looks legit. If you get a cheap SDR receiver like the RTL-SDR dongle, about $30 on Amazon and free software it will give you something like the screen shot below on a computer. Its a wide range receiver with spectral display and you can measure differences between signal...

That would be multipath distortion and at GMRS frequencies 1ft is about 1/2 wavelength and moving 1ft can potentially make the signal fade under the right conditions. Its not the signal fading due to low signal level, its the signal from the transmitter taking more than one path to the receiver...
