Join Date: Apr 2007 Posts: 553 Re: Garmin GA 28 Antenna Repair Help, Please Sounds like a GA29 which was a replacement for the GA28. If this is the antenna, then yes, it can be opened up. I'm a service tech and have replaced the coax in many of these antenna's. It is no simple task. The top part of the antenna does unscrew but the threads are coated with silicone rubber. You will have to open it with a strap wrench which means you need to make a special mount to hold the lower section of the antenna as it takes a lot of torque to get the top to start turning loose from the rubber. I used an old brass 1"-14 thread mount that I drilled and tapped a 1/4-20 hole into the side of the threads. I screw this up into the base of the antenna and align the tapped hole with the slot in the side of the antenna to allow me to put a bolt in. Then clamp the modified mount into a vise. This allows you to unscrew the top without allowing the antenna to just unscrew from the mount. Your not likely going to be able to just clamp the lower part of the antenna into a vice as a tremendous amount of torque is needed to get the top loose. You can try it, but you might just end up crushing/damaging the lower part of the antenna in doing so. Once you get it open, you have to unsolder a small circuit board that the cable connector is directly soldered to. Then you can get to the nut that holds the connector to the base. You will also need to find a replacement crimp ferrule to be able to re-crimp the braid of the coax to the connector which also means you should have the proper crimp tool, and you have to trim down the cable dielectric in order to fit up into the connector when you redo the cable end.

BTW, you first have to remove a small screw which is under a label on the underside of the antenna before trying to unscrew the top. This allows air to equalize inside the unit.

How do i get my Dynex TV to work on an antenna


Easy. First put up a good outside or wall antenna. Then run a coax cable (not flat lead wire) from the antenna to the tv. To do this you need to get a "balum" to go from the antenna to the coax wire. It's a small plastic 'transformer' (( about the size of your pinky finger)). The other end of the coax wire should have an 'F' connector put on it so it can screw into the F connection on the back of the tv set. Then get your remote and go to the input of your tv and change it to antenna input. Then do a channel scan. Let it finish scanning and it will let you know how many channels it picked up. If you're in a big city then you may pick up as many as 100 or more channels. If you're in the country, you may only pick up about 5 channels! If you need more channels then go back to Home Depot or Lowes and get an 'antenna amplifier'. Hopefully one that has about 25db gain. Most only have about 10db gain but the higher the number the better. It should be put inline between the tv and the antenna so you'll need another coax cable for the amplifier to the tv. The wire that comes from the antenna goes directly to the 'input' of the amplifier. Then from the 'output' of it to the tv. You'll love it once it's done and it's cheaper than cable or any other paid service!

Can't talk long distance seems I can only talk for a hundred yards and then I can't hear other drivers


  • Hi, I can help.

  • The most important part of a CB set up is the antenna and the coax/connectors being used. Make sure your antenna is a good one. If you want a suggestion on a good one leave a comment with your budget and weather your using a mobile/base set up. Make sure your connection is goo. Check the PL259 and make sure the braids have not split off for inside. Soldier a new one on if necessary.

  • I will give you some instructions to peak your CB and adjust the receive. Make sure the CB ha no power and use a plastic screwdriver inside your radio.

  1. Pull the bottom cover off of your radio.
  2. Put a watt/power/SWR meter inline.
  3. VR1 is your receive gain, adjust that to pick up from farther away. Note white noise can occur along with this as you will be sensitizing the front end.
  4. Adjust VR4 for 100% modulation (swing)
  5. Right by the final is a can with some glue on it. Scrape the glue off and turn that ferrite out until your power output is 4 watts RMS (not bird)
  6. Your Cobra 29 is now peaked and tuned as much as possible without using a Oscilloscope. And doing this this way will not require a re-alignment afterward.
  • Don't touch any other pots in the radio.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Regards, Tony

Trouble with remote on second TV, not responding from back of house


Hi, Mary with Dish Network Customer Service. The TV2 remote (UHF) can work up to 200 feet from the receiver but can also get interference issues that cause it to not work consistently. One of the things that I recommend is to readdress the remote to the receiver and possible installing a pigtail to the remote antenna on the back of the receiver. I have this on one of my receivers and have never had an issue since. To troubleshoot try these steps:

Step 1: Verify correct Remote being used
Check that the remote matches the TV. Use remote key or sticker on remote to confirm. TV1 is located in the same room as your DISH receiver.
Step 2: Check that UHF Remote Antenna is Secure/Upright
If UHF, check that your UHF remote antenna is securely connected to the "Remote Antenna" port on the back of your receiver and that the antenna is upright.
Step 3: Address Remote
To SAT: Access "System Info" - press and release the "SAT" button then press the RECORD button on remote control. If unable to access System Info using the receiver, use "Video Frozen/Locked Up".
To TV/DVD/AUX: Check for current remote codes and address remote.
Step 4: Check that Remote Control Batteries are Fresh
Check that the you have recently replaced the batteries. If not, install new batteries.
Step 5: Reset Receiver
If the issue is only on ONE receiver, unplug the DISH receiver for 10 seconds and plug back in.
Please note: It may take up to 5 minutes for the reset process to be completed.

If you are still having an issue, to install a pigtail you will need a piece of Coax cable, approx. 3 feet long and a barrel connector. Remove the remote antenna from the back of the receiver, attach the coax cable to the receiver. At the other end of the coax cable insert the barrel connector and add the remote antenna. Then drape the coax cable behind and towards where the TV2 is located. It takes the remote antenna away from where all the electronics are, which are major causes of UHF interference. I hope this helps resolve your issue.

I have a Cobra 29 LTD CB radio, when I hooked it up it will light up but sound and also the signal meter is not moving and it won?t tramit or receive. Yes the mic is hookup.


There may be an issue with the coax, antenna, connections, settings or a combination of them all.

Set the radio to AM, a channel of your choice, volume to just under 1/2 way, squelch to off or fully CCW. Make there is no plug in the ext speaker jack. If there is still no sound, try connecting an external speaker and try again.

Carefully check all connections for tightness and inspect the coax cable for evidence of being crushed, pinched, cut and jacket damage that could allow water to enter. Replace the coax cable if any of the mentioned problems are found.

Inspect the point that the antenna is connected to the mount / coax cable. It is not unusual for this area to become oxidized due to exposure to weather. Thoroughly clean or replace parts that can not be cleaned up.

Check the antenna for damage. If "higher than rated power" has been introduced to the antenna, it has likely failed, and will require replacement. Since CB is limited to 4W AM and 12W SSB, most antennas are rated for 25W or less.

You should obtain and connect an SWR meter with a short length of coax cable between the radio and the antenna. The meter should be rated for the frequency range of the transmitter - in this case, HF or 27Mhz (11 meters). Tune the antenna for lowest SWR over the range of frequencies by physically lengthening or shortening the whip in the base in 1/8" increments.

I hope this helps!

2001 Expeditions don't have a conventional antenna. It's built into the windows. Unless its broken, you'll not need to install a new one. There is a conventional antenna coax cable with plug in the dash that will plug into your new stereo's antenna socket. That should do it.

If its broken, look for a scratch on your glass that breaks on of those conducting tracks, like rear window defrosters, and use a repair kit to fix it.

Hope this helps.

I suggest LMR-400 cable, but generally most any coax cable will do. As far as your connectors, I suggest visiting RadioShack or The Source for these, remove your existing antenna and bring it with you to determine what N-Connectors you will need.

When you asy that you have an swr meter, you are refering to an inline meter, not the one on the radio, correct? Have you set the SWR by the instructions of the inline meter (if that is what you have)? Have you made sure the antenna is mounted to the bracket with the white plastic washer in between the antenna and the top of the bracket? You have checked the antenna coax for a broken center conductor and for a center conductor shorted to shield with a multimeter? Check antenna bracket to ground with a multimeter?
