444.575 is now online from high up in downtown Tampa! It requires a PL of 146.2 Hz. P25 is supported with a NAC of 293.
Thanks to the hard work of our members we were able to bring this online over the weekend. It is a “Proof-of-Concept” repeater designed to cover downtown Tampa and the central business district buildings. This necessitated a lower gain antenna for solid coverage below the site and in the surrounding ground level.
The repeater consists of the following:
- 25W Motorola Quantar
- DB-404 Antenna
- Mobile notch duplexer
- DB-404 antenna
- 3/8″ feedline (2.3 dB loss)
We plan to change out the feedline to a higher quality Heliax cable which should improve the receiver.
Below is a projected coverage area of the repeater to a HT at 5W. We’ve had good mobile reports much further than this shows. Please try it out and report back on our mailing list.

Below are some pictures of the repeater site after we got done.
