It's slim pickins for new, Part 95 hardware. There is a bunch of grandfathered hardware out there, though.

You really want them to go nuts. After you tell them why, run a script that has it trying to track different sats. So the assembly is going nuts tracking and skipping to another sat and goes nuts again seconds later. Chance are they will grab a sledge hammer and help you tie down some guys through the asphalt.

Just tell thjem the white house asked you to put it up for the testing of their early detection of incoming UFOs. Once it starts tracking they may shut up.

LOL They are mad that my 1984 pickup is in the circle. Plus, within minutes of putting it up, I was asked by one of my neighbors how long the eyesore (portable) was going to be in my driveway for. I can imagine how they would respond to a nice parabolic or steep take-off beam on a single axle trailer out in the middle of the circle. hahaha

MarcSpaz showed a portable antenna on a mast in the following post. He was kinda enough to put up the SWR number he was seeing both with the Diamond x30 and x50. I could of swore they made a commercial variant of the antenna designed for about the frequency of GMRS. Not sure what the numbers or model were. https://forums.mygmrs.com/topic/1723-new-portable-repeater-antenna-setup-is-done/ It was laird and comet, that made antennas closer tuned closer to the GMRS frequencies. Not sure how well they work. . https://www.theantennafarm.com/catalog/comet-ca-f72gf-1067 You also have the likes of Ed Fong, who customize to your desire, you just have to provide the outer shealth (PVC), which is a jpole design.

Also, don't forget the other stuff you can do, like EHF, Satellite communications, etc.

Don't you live in a circle? I know where you could put your satellite antenna. Lol your neighbors might get the pitchforks out though. Sent from my SM-G975U using Tapatalk

A ham in neighbor hood. Love the trees for his long wires. Hated it for the satellite work. The 2m uplink was fine but the 70cm downlink was constantly wrecked in the the summer due to the leafs.

Unless you have an antenna that doesn't require an external ground plane, you have no choice. Generally speaking, foliage will always absorb some RF energy. However unless you are trying to communicate through dense vegetation, it should still work fine. One of my antennas are in the woods behind my house, below the tree line, and I get great performance out of it.

Should also add don't forget the feed line losses of the given line of coax... that could easily sway which way you go. Any gain from antenna design could easily be lost by choose the wrong feed line or being cheap about it. Feed line loss gets pretty bad the higher up you go in frequency. A piece of coax might have a loss of 1.2db at 144mhz but at 470 it might be 6-7 db loss per 100 feet. That is without the connectors.

now that's just ridiculous who needs that much cushion on a seat

A few errors here. GMRS regulations were updated in 2017 and are now Part 95 Subpart E The full text of Part95E is available here. To be legal on GMRS, radios must have been type accepted or certified for: Part-95, Part-95A or Part-95E The icom IC-F6021 is Part-90 certified, but not certified for GMRS. However, it will operate on GMRS frequencies.There have been several discussions about using Part-90 radios, and other "ham" or Part-15 certified radios on GMRS. Many people do this, many don't Search through the threads and you can read the various opinions.

Sigh... wasn't letting me add the JPG. https://i.imgur.com/mVih2uV.jpg

There are 1659 repeaters listed at myGMRS.com and assuming that 20% are inactive and or otherwise not on line, that still leaves 1328 repeaters. How many of those are WB versus NB? I would submit that most of them are surplus WB "legacy" repeaters. Many owners have a ton of money invested in them, so if GMRS were required to go NB only, I'd bet that many of them would simply pull the plug, thus impoverishing the utility of the service.
