Two Repeaters One Antenna Feed Line

Two Repeaters One Antenna Feed Line

We had an opportunity recently to provide a unique duplexer system. The customer needed a single antenna feed line for two repeaters. This solution saved the customer two costs. One, the expense of hiring a tower climber. Also the recurring cost of additional tower space rental for a 2nd feed line and antenna. This is perfect for Amateur and Commercial applications.

Watch the video to hear Ron describe the application and solution. 

 Application Notes:

 Minimum Frequency Spacing 2 MHz between RX

Hi! This is very interesting! I’m in the same boat. I have one antenna available and wanting to add a second repeater. I get how the notch duplexers have to be set up. But i’m a little confused on how bpbr duplexer aligned for the frequencies? Coming from the TX and RX notch duplexers? A little insight would be great! Thanks for you time! KD9HDR

I’d sure love to see any additional information about this as well — I’ve got an application that this would simplify if it was practical, but hard to even consider without some additional numbers — such as loss, cost, etc =]

Thanks for sharing. Is that like a poor man’s multi-coupler / combiner?

Would you be able to supply and tune the equipment for us if we had a similar need. If so, what would that cost be?
Also, what are the restrictions, ie freq spacing, power min / max, etc…

Thanks,

Wouldn’t it be nice to have seen ANY data about insertion loss, cost, etc. My guess is another antenna and feedline would cost less than this combo. I understand that wasn’t a choice with this customer. I’m guessing at least 8 dB loss ?

Hi Ron,
? on the 2 UHF repeaters on 1 antenna. What is the max power input to the duplexers allowed from the repeater PA output and how much avg. power is lost through the system at the antenna port? (450-470 mhz band)
