Bidirectional Amplification - UHF-T band

[KC2ZHY]

Hey guys,

I am looking for input on a bidirectional amplification system for the UHF-T band (i.e. 470-512 MHz). Long story short: the trunked radio system in my county provides little-to-no reception at the medical center in the two most critical places: the emergency department and the basement level where EMS is housed. I understand that trying to find something that covers the entire 42 MHz bandwidth may be asking for a lot, but it's the only way to ensure coverage.

Jack recently passed away, and I don't know if there was anyone to take over, but the website is still up, and there's still some good information to be had. There are UHF BDA's that are manufactured that would work perfectly in your circumstances. They're not cheap, but done properly, you'll get seamless coverage, and your users won't be able to tell it's a BDA.

A Google search will out you in touch with vendors. There are now Class A BDA's using DSP filtering that have some pretty amazing performance. Class B BDA's are cheaper, but you get what you pay for, and they may not actually be legal in your circumstances.

If you can afford it, I'd strongly urge your county to hire a consultant to either write a bid specification, or do the design and oversee the installation. BDA installation in a hospital is tricky, and among other things runs into HIPPA regulations, as well as local building codes. It's not a good venue for a beginner to learn how.
