Pointing the dish could be accomplished over a much lower rate and more robust radio link. On Wed, Jan 21, 2015 at 3:47 PM, Tom Hayward <tom@tomh.us> wrote:
Very cool... We have joked about mounting a dish on a rotator, but never actually done it permanently. It would solve a few problems and be fun for testing long shots.
But then it could create a few problems too: obviously, increased expense; a strong gust of wind could turn the rotor, bring down the link, and eliminate our ability to remotely steer the rotor back into place; and the rotor would need to be geared low for precision aiming.

This was also in the ARES E-newsletter. Worth noting is that there are WinLink products and users on this Emcomm LAN. It is based on PtP distribution, with a some Point to multi-point. It differs from broad band hamnet in that it is all stock Ubiquiti products based non-modified, does not use node like connectivity, and no part 97 restrictions. But those BBHN out there are doing the same thing as far as product distribution, just the Baja-San Diego network went a different direction. Both work in the same venue of IP client-server distribution.
Winlink products include HF gateway with auto forwarding that USA side can take advantage of. RMS Express PtP telnet users. RMS Relay Post Office in service. Differeing packet gateways using LAN to reach common RMS Relay.

Update on San Diego/Baja High Data Rate Emergency Network
There is progress on the HDRENS (High Data Rate Emergency Network of San Diego) project: Our team has just completed installation of a new high data rate relay point on the University of California, San Diego tower, located on Mt. Soledad, California. There are two dishes at the top of the main structure of the tower; one is for a 5 GHz link from our central radio room location in Coronado, California and one 2.4 GHz dish serves as a relay looking out into our "client territory." Both dishes are on rotators. The 2.4 GHz link has been positioned to serve a number of our active ARES associates including our ARES EC Bruce Kripton, KG6IYN.
The TX/RX data rates we currently measure on the 5 GHz link are in excess of 50 Mbps. Our long range plan is to continue to expand the high data rate network up the coast and inland to provide high data rate private LAN backup for more and more emergency communications clients including those San Diego County hospitals that choose to participate.
The Mt. Soledad installation will now serve as a key relay point as we reach out further into the lower and central San Diego County region. We continue to share the high data rate emergency network with our sister organization, CREBC, in Baja California, Mexico. -- Ed Sack, W3NRG, Coronado, California
