Yes you can. Some models require a bit of digging.

No problem, I have them sitting in my cart atm. To retain them better, with the screw removed put a small dab of silicone or rtv in the pin side of the screw hole. Use a tooth pick to poke a small hole in the rtv as it dries for the screw. If you need you could also use a dremel to slot the top of the screw for easier installs.

My local home depot has it in stock, alternately you can find a four pack of thumb screws in M2.5 on Amazon for $6 HARFINGTON 4pcs Vernier Calipers Locking Screws M2.5x8mm Round Flat Head Knurled Thumb Knob Bolts https://a.co/d/eQVljlR

Cable extender? The feed line of RG-58. It’s only 16’ so loss is not that bad. Not really noticeable. I run one on top of my van, feed it with a 5w HT and haven’t noticed any issues not already present In the radio it’s self.

M2.5x0.45 is what I’ve seen source https://coderedheadsets.com/content/manuals/TB_Baofeng_UV_9R.pdf

Ut-72g isn’t bad for a magmount

I use the MeanWell LRS 150-12. Its bare unit, so you have to figure out your own cables and enclosure. https://www.amazon.com/MEAN-WELL-LRS-150-12-Single-Switchable/dp/B018RE4CJK What radio do you have?
-
Second or third the AT779UV for value/dollar. great for car use, base station or “man pack”.

I went from a roll up jpole at 30 ft, that on days when conditions were optimal could get into repeaters 45miles away to a higher gain collinear that can get into the same repeaters with out problem when conditions are bad. Each antenna has its use. Some are better at filling space and some are better at pushing signal at greater ranges.
-
That’s awesome! Next time you go out, try taking a higher gain antenna like a yagi or coax collinear.

Terrain effect on line-of-sight communications

All those…curvatures… -
This is correct, if you want to program any repeaters in above channel slot 30 with the ability to TX, you need to use chirp.

Popularity of GMRS with Over-The-Road Truckers?
Borage257 replied to Lscott's topic in General Discussion
Now there’s and idea, a lunchbox repeater mounted on a semi. Antenna up on top of the cab. -
Have you checked the MYGMRS map with “Stale” and “Offline” repeaters turned on?
-
RadioMobileOnline is pretty good
-
Have you used the map portion of this site? It does load slow on some machines, but it is pretty much google maps with an overlay If you switch to “colored streets” or “out doors” the map will respond faster. I have yet to find a better repository of GMRS repeaters online.
-
Get one anyway for ht experimentation! See how far you can simplex between your ‘base’ and a ht w/yagi.
-
Ammo can build in progress, the plastic box on top has a MEANWELL LRS150-12 set at 13.8v Antenna is a N9TAX roll up at 30’ on some secondhand LMR600.
-
@PartsMan add a yagi and you’ll really get some range!
-
The repeater section of this website. Also the map. Unless there is a lot of noise on your RX frequency , leave the tone off.

Electrical tape

DB20G isnt bad for the money, makes a good ammo can radio.
-
The more height your antenna has, the further your range. If you get your antenna up about 30’ you should get some decent range.
-
The 70cm is close enough to GMRS frequencies to get a good idea of performance. Many 70cm antennas can be used with out problem on GMRS. The Nagoya 771g will likely be a good choice. Smiley antenna has a good 465MHz antenna line that is equivalent or better than the Nagoya. I think the ABBREEs are more of a novelty/“Airsoft” antenna. They work, but I find signal stick, smiley and Nagoya to be better
