UHF is very line of sight So height is mite Uhf 1/4 wave and half wave +2.5dB on HT Helical stubbys tend to -3 to -6db loss gain on uhf. Terrain locally on uhf can have a massive effect on range Enjoyed the video 👍
If you want to get into GMRS radios the demo you see here is good to understand. Line of sight (even through fog) can go 10's of miles. Or though trees... one mile.
Technically line of sight is 17 miles due to the curvature of the earth. Needless to say depending on the relationship of the user and repeater range can be very high in the hundreds of miles.
Should of said on stubbys antennas best using 4-5w as ERP will be around 0.5-1w ERP about -3 to -6db loss 1/4 wave 0db loss so full ERP 1/2 wave 2.5db gain so that doubles your ERP(effective radiated power) For ref 6db=1 S point 3db=1/2 S point Hope that helps understand? UHF is very line of sight,wish we had high power gmrs service in UK 1/4 wave generally ok stock at uhf. Wouxun are a very good brand too 👍 Rob Rob P
I stand corrected, you do mention it in the video, but in the description, bath county doesn’t mean anything to a non local. We have the same interest (radio) just saying. Good video. I really enjoyed the different antenna tests and effort 👍🏻
That’s a loaded question a depending on who you ask no one can seam to agree on. the best answer I can give you is contact the fcc and ask them and request the answer in righting. There surprisingly willing to talk with anyone.
@andrewdaniel7873 like I said before it depends on who and when you ask. Iv personally asked a nameless government organization 9 times and have gotten 4 different responses. With as many linked repeaters as there is this tells me the “rules” are not written as clearly as some people want to believe they are. my non legal advice is do your own research. Go into the conversation open minded.
Because I was using a repeater that was several miles away that’s not mine. And for the “weak signal” test the audio came to my phone so there wasn’t a need most parrot repeaters have static on them also. thanks for watching
This is far from a scientific test, nor was it meant to be. Since we live in the real world and not in a scientific laboratory this test shows you real world data. Something Is only a waste of time if you make it a wast of time. Thanks for watching

Good informative video.
Thanks for watching
Great video.
Playing with radio is a good way to build a community.
Go full ham, you'll love it.

I’m thinking about it. But the Ham people in my area take radio a bit to serious for the average person who uses a radio in a normal manner
Hold the signal stick straight up
If you have to split hairs is it really better? Thanks for watching
@@JDubbsadventure check out Ham Radio crash courses reviews on the signal sticks.

This is true, the trees really hurt your range. This applies to all vhf and uhf even though vhf is a little better for longer range

Good information but it’s Way to technical for 99% of people that just want to know can I talk and can they hear me
@@JDubbsadventure ok thanks,just use 1/4 best ,if 1/2wave available use that even better on uhf.
have fun ! 73s rob
Georgia, Alabama, or Mississippi?
Wrong Virginia. I even say it multiple times and it’s in the description

Why can't repeaters be linked, or can they? I am not very radio savvy.
Look up "North Georgia GMRS" for the answer.

The official rules say they can’t be connected via any wireline link (meaning telephone or internet) however, they can be controlled remotely

I gotta get me a GMRS radio and license. I've been a Ham for years. Do you ever talk into any repeaters in eastern KY?
Only takes about 5 minutes to get the license an the kgq10g and the kg935g are great radios
@@ricdonato4328 I put the call sign on the radio as a “header” it’s always up there and can’t fall off but not all radios do that
why not using Parrot repeater, for check your antenna.
Because I was using a repeater that was several miles away that’s not mine. And for the “weak signal” test the audio came to my phone so there wasn’t a need most parrot repeaters have static on them also. thanks for watching
roger.. copy that
Been looking into gmrs for emergencies. Not really impressed.
If I may. What’s not impressing you?
The only true way to measure any antenna is to use a service monitor, any other way is just a waste of time.
