I installed the midland 1001z with a window antenna it worked fine. I've since upgraded to an whip antenna and grounded it to the exterior of the vehicle. but now the s/rf meter dances about on receive or transmit. When transmit would usually go full red, now is just doesn't light up or bounces into green a bit.

Re: MIdland no sound s/rf dancing
May be u burned yr final transistors...check if yr antenna is well grounded and try just after this to transmit, if the indicator is not stable on the green area when you are in "am" modulation stop to try and bring to the assistance

The fiberglass provides no ground plane area for the antenna and radio waves. Your Standing waves (aka: SWR or Reflect) are probably very high. I suggest mounting the antenna on the cab of the truck. You "could" try aluminum tape on the cap and mount the sheilded side of the coax to it somehow. Without a ground plane much of the RF Power of you CB will be reflected back to the Final Output Transistor(s) (Final or Finals), overheat it and possibly damage and burn it/them out. If you are just running the CB without an amplifier(Linear or sometimes called a box), a magnetic mount antenna should work fine and be less of a problem than permanently mounted antennas. That's a plus when going into a parking garage. Even if you decice to get an amplifier at a later date, you should be able to use it with the magnetic mount antenna as long as the antenna you but is rated for several hundred watts, you Standing Waves are Low, and the amplifier doesn't put out more power than the antenna is rated for. I hope this helps.
Try Grounding it better. Its supposed to equal 8.5 ft.(102 inches) but the coil may make that in all.You can clip like 1/8 inch off at time until it goes 2.1 Swr. Thats a good standard. 1.5 SWR is desired. If it don't have a coil with it that may be the problem. You could turn it into a 8.5 ft. antenna by buying a 102" inch whip to screw into the base of your antenna, it depends if it holds or not. You could build you a matcher like this with a solder gun+solder and 2 resistors. Get you a box with 2 female cb antenna inputs. Drill a hole for both Cb antenna inputs into box. Place them into holes screw nuts down snug. Run a copper wire inside to both grounds or a plate somewhat. Run a thick gauge copper wire from center cb ANT INPUT(2) to other input of ANT INPUT(1). Solder 2 100 ohms in parallel from input to Ground. If you could take apart your radio(eliminating the box idea). Just Solder 2 (100 ohm) resistors to your Antenna output then put it back together. 50 OHM MATCH HERE Is the main idea. I've used 75 OHM Tv coax and reduced SWR.
This could be several things, first I'd look at your antenna system,make sure its matched to your truck. When I say this you need a good ground good coax at least 18 foot,the mount and it installed right and the right kind of antenna, they make many different one because not all work on what you're installing it on. Then I'd check your mic if it has a broke wire it can also cause the problem you're having, most midland mics are wired different so don't just find another one.
I had the same (squealing) problem on transmit with the Midland 1001Z
when I used it indoors as a base unit. The problem was my power
supply: it broke into oscillation when drawing more than 150 mA at
13.8V. The 1001Z draws about 150 mA on Receive, and much more (but
only about 900 mA) on Transmit. If using the 1001Z as a base unit, I
suggest you power it with a fully-charged car battery indoors, or test
your power supply to check if it can't supply the required 1 Amp,
approx., on Transmit. It's a GREAT radio, just give it a good power
supply. My power supply was defective out of the box, but now I have a
good one and get great reports on signal strength and audio quality.
Remarkable, for the low price and 3 year warranty. Good luck!
First off, Midland makes a fine radio. Make sure your squelch is turned all the way down to receive distant signals (down meaning counter clockwise). The through the glass antennas are not the best thing in the world. I personally use a 102" whip and a 6" spring on a modified mirror mount. It is installed on the tailgate side of the tool box. The TX and RX is amazing. Wilson and K40 make great antennas also.
take a 9 foot wire to the bad radio put the the wire into the center of the ant jack a see if you can hear your buddy glass mount ant are ****.
9 foot whip is best in car/truck 4 foot fiberglass cophased are next 4 foot are next mags are ok but over time and moving around they will mess up you paint
Running most any regular cb, including this one barefoot (with no kicker), having a good antenna, set up with a good ground plane or a no-goundplane antenna, good coax; basically everything in good working order, you can usually bank on about 4 to 5 miles crisp and clear, and at least 6 to 10 miles fairly clear. Of course the further out you get it will start to fade out.
Some radios do better than others, but those are the general numbers I have seen in my years of experience.
