WRVD brought up something I was wondering about. Thx for that. I'm also curious about the different duplexers. I've heard the term notch used. Is there a thread about duplexers that already exists so we don't beat a dead horse about duplexers?

I think Randy's videos helped me understand the tones keep me from having to listen to others but offers no privacy at all. What I wasn't sure of was whether farmer group A and Wrtz family B could use the repeater simultaneously

But to make sure I understand, the two different groups with their different tones could not transmit at the same time, correct?

Thanks for the replies. So because I'm new to repeaters this may be a dumb question. If I put a Retevis repeater on a grain bin would I be able to program it to operate on one set of frequencies for the farmer to use and a second set of frequencies for my family to use?

So in the top picture, the higher the gain, the more focused or narrower the beam of RF that's emitted, correct? And using the lower image, that particular antenna radiates more RF to the right because that's the larger cone coming out in that direction. Am I understanding this stuff correctly? I'm not a HAM and don't have lots of radio transmission experience but it's always interested me....

Absolutely, I think I've seen the radio wave disbursement pattern with antennas before. Not sure what the actual term is for that with colors and blobs going out in different directions from the antenna. What I don't know is if on a 50 to 100 foot tall tower there is much of a dead spot area to be concerned about or if that's more for the big boys that have antennas way up high. Along the same lines, I think mygmrs.com will email me to tell me to mark if my question was answered but I don't know how to do this. Are you familiar with how to say, "yes, it helped me"?

Thanks for that explanation Sshannon.

Can someone direct me to where I can learn about what it means to have an antenna with "gain"? In the context of a repeater antenna, does a higher gain omnidirectional antenna have a larger "dead spot" area near the tower then? How does one calculate what this dead spot size/area is? Or does it really apply when doing shorter tower hights of 100 feet or less?

What do experienced installers do to choose which antenna for such application? I saw an omnidirectional Laird 4505 and other antennas but there's a lot to weed through. So how do you decide?

Thanks for that WRKC. I've got a couple farmers I still need to ask and the answer very well may be no but can't hurt to ask. The local sheriff has a tower maintained by RA Comm so again, that answer might be a no as well but can't hurt to ask. The grain bins are the only other tall option around.

I'm curious if any of you have experience with installing repeaters on tall grain bins/grain legs or Harvestore style silos. If so, how did you protect the repeater from the elements and were there any unique challenges to using a silo/grain bin compared to putting a repeater and antenna up on a tower?

Then I saw this and started to get excited but it's DMR.

The suspense is killing my hemorrhoids. When will this mystery company release more info on a 40 watt repeater? I wait not so patiently for Xenu to bless us with such a device.

I learned about a website called lidoradio.com that might be helpful to some wanting additional mounting options. I'll take a look at the cupholder holder as well. Thanks.

Im curious if others have ideas on how to make a portable radio stand/holder for a small mobile that I can easily take the radio between a half ton pickup and a small SUV. Anything out there that fits this need already?

Thx for the update WRVD. I think you said you're around the radio a little more on the weekend so I'll have to drive down your way and do a little test of my lip mounted Tram antenna. You teased me with the possible 40 watt model possibly coming out so I'll be watching for that release date. Happy New Years to you all

My misunderstanding. I apologize for that. I do appreciate the sharing of knowledge here so it is not my intention to offend.

No it was not. I do not promote anything on here. I ask questions and try to learn about GMRS and radio in general from those with more experience than I. I think I may have asked if the KG-1000G could be unlocked and if I didn't ask it, I sure was thinking it.

It's a Chevy Silverado.

Has anyone else heard of such a repeater coming out soon?

Anyone have a strong fender mount that works well for a 2m/70 cm/GMRS antenna? I found one on Amazon. https://www.amazon.com/HYS-TCJ-N1-Bracket-Fender-Antenna/dp/B08FX6T78H/ref=mp_s_a_1_1_sspa?crid=WG8RAFXDWV8F&keywords=fender+mount+nmo+antenna+bracket&qid=1671826511&sprefix=fender+nmo%2Caps%2C199&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyRU9RS0FVT1JNUk4wJmVuY3J5cHRlZElkPUExMDM5MDY0M1VLUlc2OEs5UzlQSCZlbmNyeXB0ZWRBZElkPUEwODQ4Njk3MVg1VlM2UlJBOE45RiZ3aWRnZXROYW1lPXNwX3Bob25lX3NlYXJjaF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl

So theoretically the Anyone uv-778 or Retevis ra25? Are there any 50 watt radios capable of this? For monitoring only, of course?

WRVD, in case you're interested there's a gentleman on the Aledo Repeater FB page with a Bridgecom repeater for sale. I don't know him personally but if you're interested I can look for his contact info for you.

Good to make it to your repeater from the ice cream shop this past Tuesday. I've tried to gain access to the local water tower where I live but at $1000/month that isn't happening. Thanks for granting me permission on your repeater and I'll try you again some weekend when in your area

Whatever traffic is on the Mississippi near me, mainly barge/lock & dam transmissions.
