Should be fine. Is the conduit on a slight grade to drain water?

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?

I had a blast this weekend on 10 meter dx.  I was able to talk to people in Italy and Bavaria and a lot of contacts to Texas as well.  All on 20 watts and a dipole at 30 feet high.  What a fun hobby.  

From my reading of the law. You can't even have it in the car/truck. Due to the fact some of those frequencies are used by their lmr and public services.

I am ham. They really don't question my gear my ham gear. I do have an sd card for my FTM400 that has all the gmrs frequencies removed to avoid any temptations

For GMRS I use a mix of Motorola LMR gear and Midland for the KISS method. Ham is mostly on Motorola gear but APRS is on the TMD700 and FTM400 in my vehicles. 
Work truck is only MSI gear so use it for all.

I know those mounts.. at least it think i know the owner/fabricator for that goldiee...

Either case, back to the op.

My current favoriteamateur/gmrs ht that i grab, is the Harris XG100P. Dream is the APX8500 HT.

For mobile, it's the XG100M and FTM400XDR both suit different digital modes.

For the base, I use either the CDM1250 or XTL5000 for GMRS. The FT991a for everything else amateur related, can't mod the UHF/VHF side sadly.

Think its because the average person sees extra antennas, it's got to be the police/military.

I remember parking my van at a 7/11 to go inside for some stuff right after the attack on the World Trade Center. I had a bunch of rather weird looking antennas on the top. I had a lot of people staring at me and the van. Maybe if I had been wearing a black suit and sun glasses it would have been even better. 🤣

Oh.. yea I agree. Listen to aprs frequency in a dense area.

What I was referring to was the amount of data that can be sent. Especially, something like FT. Damn symbols rate caps, lol

Good question. Even my amateur radio gear is the same way. My LMR stuff, I set it and forget it, wouldn't really touch it anyways. Mostly using pl, don't really monitor simplex often.

What I wish all radios had was nuisance delete.

Standard UHF rules apply. Get it the antenna up high. 5 miles or so can be rough with HT due to terrain and obstructions.

Base stations probably would be able to do it no problem with 20w. Fortunately these radios are under $100 usually. Unfortunately, the antenna and power supplies add to the cost.

Plus your 9 year might be ptt shy on a repeater. Yes, most of the community is great but there are still a-holes out there.

Gmrs was meant for exactly what you are trying to do.

I would suggest looking at cheap ip ht radios as well. The conversation will be local to your group over an internet connection. Yes, it's not true rf to rf. But hey you are trying to fan a spark.

I would also suggest looking at getting him on a Santa net. Dstar has one, requires a Dstar radio. If you are a general with a decent setup the wheelers have one on 80. You know where another ham relays to Santa, so the kids can talk to Santa at the North Pole

As well as people like me whom are more visual then auditory. I find it easier to identify signals and their types visually than listening to the signals.

Doesn't hurt that the entry cost for it are as minumum as you want. So it is worth a try. Usually, a cheap RTSLDR dongle is under $80. The software for basic usage is free or minimal in cost. Tons of articles on setting up antennas. There is very little that is as cheap with the same flexibility and versatility in the radio world.

It’s a radio receiver that’s controlled by your computer.  It’s extremely flexible, allowing you to listen in on almost any mode over an extremely wide range of frequencies. Because it’s controlled by your computer you can manipulate the received signal and view it however you’d like.

I get it. But some of the newer people might be unaware. That this opens up the radio to lmr 2m/70cm band and amateur radio lmr 2m/70cm. There is a reason there is no skill test for GMRS and locking down of the radios. Not going to get into it further either.

Learning that it was a gmrs repeater thing explained enough to me for now. Want to of course get me a technician's license, eventually..

Oh, that won't be very popular. 😵‍💫

A distinction that I would not notice, if you hadn't pointed it out. Fishing for knowledge in the wrong creeks 🙂. Getting some strong bites now!!

Glad you are getting it.

I should rephrase the part about listening to the output. You "can" transmit it just will go over simplex not be heard by the repeater.

Is it a non gmrs repeater?

Why I ask? The gmrs repeater frequencies are set by the FCC. Set with a +5Mhz offset. Unlike amateur radio repeaters, you can not have a reverse offset and remain compliant.

Even then a way to "monitor" a repeater is simply listen to the output frequency. You just won't be able to transmit.

For the db20g, you can three finger salute the radio in "open it up". So you can bypass the firmware locking for GMRS. I don't condone it.

This band plan?
 1270.000-1276.000
 FM, digital
Repeater inputs, 25 kHz channel spacing, paired with 1282.000-1288.000
 1270.000-1274.000
 FM, digital
Repeater inputs, 25 kHz channel spacing, paired with 1290.000-1294.000 (Regional option)
 
Yeah, doesn't seem to correspond with FM; you would see a carrier down the middle. Digital is possible but what digital modes grow in bandwidth and then shrink; they're usually as fat as they can be within a set deviation.

No. I don't have the equipment to determine power loss, nor do I have the interest to do so. I related my experience and results to let others know that a glass mount antenna is a viable option to mag mounted and NMO mount systems. While not the best solution, it is a workable one that might be of interest to others that are unwilling to drill a hole in their cars roof or don't want to have a magnet mounted antenna.
