Plans

In cooperation with NBAM, we put a Ubiquiti LTU radio here (Oct 12th, 2022) on one of the sectors and point the sector at 40°. We will experiment to see if we can establish links from ORCA, CCCC and San Pedro using Ubiquiti AF5XHD radios and 30 dBi dishes.

First experiment (Oct 12th, 2022) from ORCA was inconclusive, but test conditions were challenging (wind and fog). A link could be established, but the signal was intermittent. It might be necessary to adjust to tilt of the Woflback sector to be 2° up to counteract the in-built electronic down-tilt.
