You left the "sh" off.

While a relay is not needed, some like to have one so that any accessory wired directly from the battery will not receive power until the vehicle is turned on. This is quite common when adding accessory lights to vehicles. And it keeps from killing the battery if you forget to turn the accessory off.

It is the recommended method for any mobile two-way radio. Not enough to matter. Why?

I personally would not try running anything more than a 25 watt radio from the cigarette lighter/accessory port. I would personally just run the positive wire to the battery and the ground wire to a good chassis ground. Anytime you power a transceiver through the vehicle wire harness you take a chance of getting RFI issues. Now if you are worried about a power drain, you can use a 12v relay that won't power the radio until the vehicle is started. Here is a diagram showing how to wire a relay. So you would run a wire from a power source that is only on when the vehicle is running to 86, that will only close the relay switch when the vehicle is started. And you can use a fuse tap for this. You still want to run the radio positive to the battery positive and the radio ground wire to a chassis ground. For the relay, to work, run the radio positive wire to the relay 87 pin and then another wire from the relay pin 30 to the battery.

I had been using the UT-72g for a little while, and I had no problems with it at all. I am very new to GMRS, but it seemed to perform very well for me. I just recently got a MXT-A26. I have only had it on for about 2 days now, and the weather has been really bad, so I haven't been able to use it much. We also don't get a hell of a lot of GMRS traffic in our area. So I really haven't been able to compare them much yet. But the UT-72G seemed great for me. I also live in Southern Colorado, by a lake, so we have some plains and mountains.

Someone posted here not too long ago on how to do it but I agree that it would be better to just buy the ham version.

Would this be the same for a 40 watt radio? Would that still have a slight trickle drain on the battery? Can I use an add-a-fuse tap to power it from the fuse panel?

How do you know it’s not working? What are you trying to do? What have you done? What isn’t working?

Some times deals are not deals. What brand heliax are getting a such a deal on?

You hit the nail on the head. People should do their research before committing to anything. Unfortunately you didn't. I just want to say there's being cautious and then there's paranoia. Worrying about something that has way less than a 1% chance of happening will just drive you crazy. Don't do that to yourself. Don't do that to your family.

Give us point A and point B. With that we can determine the LOS. You may be fine with HT to HT -- on a good day, down hill with a tailwind. You're welcome. And welcome to the site.

I have the 712efc and the paperwork that came with it claims 9.8dBi. It's on the bag and in the paperwork so that's what I assume it is. So it's even bigger than 7.2

I have the RA87 and have used both Chirp and the Retevis software to program. From everything I am looking at it sure seems to be programmed correctly, but still not working. Is anyone willing to send me their programming image file to compare? Thanks

Disregard. Misread Post.

Del Webb does not skimp and they are pretty savy at making deals i.e. my buddy gets his internet as part of the association package, no extra cost. Del Web make deals with Broadband providers whom they choose to allow to come into their properties. He gets a basic 300MB package free claims thats all he needs. I get about the same with my Starlink on my RV and it works great

I put this up in my attic for my repeater. It's just a backup that I can switch to in case of lightning. It comes with or without the ground plane kit, i recommend the ground plane kit. I haven't given it the distance test yet.

If your antenna is 100 feet in the air an additional 1.5 db might be worth it. As you increase db the antenna's radiating pattern on an omni-directional antenna gets flatter. It sends more of it signal to its horizon. I would recommend plugging the info into a one of the free typographical antenna coverage calculators to quickly ascertain if it is worth it. They changed this tool it seams. It use to allow you to map it out and set each site differently with gain and antenna values. This is what I use to recommend. https://www.scadacore.com/tools/rf-path/rf-line-of-sight/ Have you thought about a yagi on with a TV rotator? Sent from my SM-S901U using Tapatalk

Nope totally wrong. Tell him to kick rocks. If you had read the fcc rules that you already signed that you read you would know this. His pants are probably still on fire.

I use a comet 712efc. It’s awsome from my location with a 20w radio 200 miles is no problem. I also have a 9nc with a 50w radio. Not much difference in distance just more clear but boy can I hear everything much more clear. I always say get the highest gain you can. I have no negative effects in close.

I've got a repeater set up at my house. My antenna was damaged but I was able to fix it. I'm looking at replacing the antenna anyway. It's currently rated at 7.5db. I can get a comet that is rated at 9db for around 150 quid. I'm going to replace it either way, I'm just wondering if the extra DB and a half will make a noticeable improvement. I want to get the highest performing antenna I can under, say $200. It seems like there's an astronomical increase in price above 9db. The cheapest 10dbi can find is $2,000 it goes from $150 to $2,000. The antenna is mounted as high as I can get it and I've replaced the coax. I found a deal on 1/2 inch heliax.

Im in a similar situation as you. I work near LAX and Wife is at home. We use a set baofeng UV5g plus HTs with the longer antennas we get about 4 miles on simplex HT to HT. I have a Retevis RA87 in my car she can hear me about 7 miles from home but i cant her her until the 4 mile mark on simplex. We are members of The Mesa Crest Repeater club. Using one of the clubs repeaters on either MT lukens or Santiago peak we can talk using the HTs from our home near the 605 and 405 FWY interchange all the way to San Clemente ca. If I switch to my mobile I can reach home from Encinitas Ca.

He lied to you.. Right to your face..

For $20 from AliExpress I purchased the UV-13Pro and achieved the same results.

Third! He was completely wrong. No such notification is needed or even possible.

I second that.
