  1. TYT TH9000 UHF GMRS REPEATER SETUP?

    in Technical Discussion

    Posted

    Good news all your help is appreciated. We are using the radios without a repeater an getting good range, perfect for our area ...the rated 8dbd ground plane antenna is 4 feet up on the crest of the roof of a single story...reaching about 8 miles out.

     

    I tried sr628 with the aggregandizer style configuration through the back of the radio using db9 cables and it works up until side a/b requires input then about half range...maybe if the antenna was higher could get a good signal in a 600 +- split frequency at longer range but i dont see why i wouldnt go simplex in this instance. I havent tried any other repeater.

    Hi everyone...apologies for the delay. After all this time ID like to report with results. The sr 628 distorts the signal drastically and the distance decreases dramatically while in use. It works great but needs high output maybe a preamp but for now, the th9000 is bare and were getting good range with a repeater. The setup is a simple sinc labs gmrs antenna on the crest of the roof about 4 feet above it wired straight through a 4ft netting pole..its pretty much tree level And were getting just about the coverage we need its great . The vehicle Is sporting an old bus antenna its great. U guys helped alot for the record thank you

    A good bit of your range depends on what type of antenna installation you have.I suggest you get a decent repeater capable antenna and a few other members can recommend those to you.I also strongly suggest at minimal LMR400 feed line since the loss will be minimal compared to RG-8.I would not worry about call the FAA or FCC unless you are planning on installing the antenna above 200 FT.

     

    You also need to get a good controller and have it wired to your radio system by someone who has the know how to figure the correct wiring scheme along with having the duplexer tuned by a professional radio shop with the proper equipment to do so.You will not be able to communicate well unless this step is taken along with the good feed line.

     

    I wish you luck on getting your GMRS repeater up and running,you had the a few of the basics covered and with the help of others on the forum you should be able to get the advice you need to have a good set up...William

     

    BTW thank you guys for taking your time to provide input..! Some People who it's taken years to learn all this knowledge would not be very inclined to discuss such details..of course we all know that "radio people" are indeed polite and considerate...at least that is my experiences...so I'd like to express my gratuity to yous guys..

     

    Spd641 I actuality was hoping someone would have had experiences with setup of this system with these radios... I read there was a port to the rear of the housing of the tyt radio for a terminal that could easily be installed, but is not inside it....I guess I'll have to discover how on my own and report those facts here...the programming aspect can be tedious routing pl ctcss etc..if I could only get these issues resolved then the fun begins and we'll be enjoying the fruits of our Labour!

     

    I was curious to know if any of you knew of scrambler function and if it's a viable option using gmrs?

    well good point im starting to believe it may work...i ran the pole up 20 foot to the peak of the roof and then mounted the antenna.... i have a 40 foot tall tree i am debating on mounting this jpole to which hopefully works well...i have painted it white because of the ho association issue but will furthur camo it by adding light sky blue if it goes up in the tree...i am really hoping it works. the install is in a suburban area of florida with subdivisions stores and homes and condos..we have plenty of old oak trees and pine trees as well as numerous other gargantuan trees...i ran it from the peak with a simplex repeater and literally got a half a mile radius...ridiculous i know but it was basically all i could do to test it out..also had someone else keying me up to test...also tested with handhelds same issue even with using the mobile to relay so the antenna is the final hurdle before i give up on the gmrs and sell it all!

    Ok I wouldn't mind if anyone else wanted to chime in..thinking of going with surecomm , hoping antenna height will give radios good distance...

     

    Would you elaborate antenna height makes a difference? Even if it's a 10-20 foot distance?

     

    Could I possibly defeat heavy interference and increase the tx rx distance ?

     

    Again thanks a lot!!

    I HAVE TWO TH9000 RADIOS WITH THE RT SYSTEMS PROGRAM/MING CABLE AND ILL BE PURCHASING A 6 CAVITY 50 WATT DUPLEXER...I ALSO HAVE A JPOLE WITH THE 4FOOT MILITARY NET POLES AT 20 FEET.. ID LIKE TO CREATE A REPEATER FOR MY AREA.. BESIDES THE EQUIPMENT CAN ANYONE INCLUDE KNOWLEDGABLE STEP BY STEP INSTRUCTIONS FOR THIS SETUP?

     

    ALSO, CAN I RAISE THE ANTENNA ABOVE 20 FEET? I WAS LOOKING FOR AN GMRS ANTENNA APPLICATION BUT COULDNT FIND ONE..

     

    FROM MY UNDERSTANDING I PLACE TWO RADIOS SIDE BY SIDE OR ABOVE EACHOTHER IN A COOL ENVIRONMENT WIRED INTO THE DUPLEXER, EACH RADIO IS SET AT 5MHZ DEVIATION, I DONT THINK SO BUT IM ALSO NOT SURE, WILL I BE USING THE SAME ANTENNA IN THIS DUPLEX SYSTEM?
