I like the idea of testing with a radio on the bench after tuning. Great video showing process of how it is tuned. Still have one of your XLT duplexers in use since 2021.

Excellent video - thank you for posting this.

To tune a duplexer you got to sing to it first, it will resonate in harmony with your tuning rods.

Does this require the -TG model or will the dsa-815 model do this as well?

[@TractorWrangler01]

I am interested in setting up a 50-watt gmrs repeater. The antenna will be up at approximately 100 ft at the base. How do I get 50-watts to the antenna when the duplexer sucks up watage before it gets to the antenna?

[@BuyTwoWayRadios]

Hi, thanks for your question! To answer it, we would need more info on your situation. Where is your antenna located? Is it elevated at all or is it just a 100 foot antenna off the ground?

[@TractorWrangler01]

@BuyTwoWayRadios it's elevated. I have a higher piece of ground than most of the surrounding terrain, but I need to get it up another 100 feet to be above the tree tops.

You are always going to lose power in the duplexer.
