aarondong2005 Posted February 21, 2021 Report Share Posted February 21, 2021 Hi guys, I already have Motorola MTR2000 for my repeater build. Now I need a high gain antenna for it. One of my friend already using 1480 for his GR1225 and he told me it is better than 1480. But after I check I find out the 1486 is for GMRS not the 1480. So which should I pick? I need someone have really life experience not just on the paper. The repeater will be located in Upland, California. Channel 16, 20, 22 can not be use. Which channel should I pick? Thanks!

JohnE Posted February 22, 2021 Report Share Posted February 22, 2021 I would personally spend some time listening to the channel before deciding. I spent days listening in the site where my machine resides before putting it on the air.As to the antenna the 1486 would be the choice as it is a strait up UHF antenna. I'm not a fan of the Tram/Comet antennas but they seem to be popular w/HAM's, then again I live in the LMR/PS world.what is the plan for cable?These are what I'm using. Not cheap and will last 20+ yrs on a site barring physical damage.https://d3ciwvs59ifrt8.cloudfront.net/3d2faca2-b31b-426a-8e30-d282d46d987b/8b99adb0-0d32-46b0-9f42-8c4580c6e3d2.pdf gortex2 1 Quote Link to comment Share on other sites More sharing options...
gortex2 Posted February 22, 2021 Report Share Posted February 22, 2021 I wouldn't install a TRAM antenna on a good repeater such as a MTR. Order a DB404 or 408 for the repeater if you want good performance. What does it have for a duplexer ? https://www.theantennafarm.com/catalog/index.php?main_page=product_info&products_id=4267 https://www.theantennafarm.com/catalog/index.php?main_page=product_info&cPath=191_193_258_1098_1099&products_id=4268 I'd go with the DB408 personally but I do run a few DB404 on small GR style repeaters. Don't skimp on hardline either. JohnE 1 Quote Link to comment Share on other sites More sharing options...
aarondong2005 Posted February 23, 2021 Author Report Share Posted February 23, 2021 After did some research I am thinking about Laird FG4507 or the Comet CA-712EFC now. Thank you for the recommendation, but the DB404 or 408 is too big for our business building. For the duplexer, I am thinking about getting the Celwave UHF 50w.

gortex2 Posted February 23, 2021 Report Share Posted February 23, 2021 You need to check programming on the base. Standard was 100 watts so it will need turned down. You should get a real bandpass reject and not a mobile duplexer for it. Quote Link to comment Share on other sites More sharing options...
