MESH Update 18 June 2016

Category: New Hams Published: Sunday, 19 June 2016 Written by William Moyes

A 5 GHz node was added to the DCARC Antelope Island MESH today by K7FPV, KB7YSP and N7IE.  Specifics follow: 1.  Node type:  AREDN 2.  AREDN Version:  3.16.0.1 3.  Channel:  182 4.  Frequency:  5.910 GHz 5.  Bandwidth:  20 MHz 6.  Recommended Distance setting (Required):  110 per cent of the distance from your node's location to the Antelope Island (K7DAV) repeater site (coordinates 41 deg 00 min 52 sec North; 112 deg 12 min 29 sec W). 7.  Required Equipment to Access:  Ubiquiti Rocket M5 (Version XM); Ubiquiti Nanobridge M5 (NBM5);  Ubiquiti Nanostation M5 (NSM5).  Note:  The Rocket requires a separate MIMO antenna.  The Nanobridge is a self-contained unit similar to a Dish Network (r) dish and feed.  The Nanostation is a compact unit that is intended for a wider beamwidth and shorter distances.  Note:  Not all of the listed devices may access the Island site from your particular location.  A clear Fresnel path is needed. General:  The new node is a Ubiquiti Rocket M5 feeding a 120 degree MIMO sector antenna pointed generally east.  Coverage is expected to be Davis County and the north and east parts of Salt Lake County.  It is integrated with the 3.4 GHz node at the same site described in a prior post via a switch in a device-to-device (dtd) configuration. The Question:  Perhaps the obvious question is why wasn't a 2.4 GHz node installed on the Island?  There are a few reasons: A.  2.4 GHz is expected to be used by local groups of hams to install Meshes in their local communities. B.  The Island site is considered to be part of a backbone/backhaul system to provide wide area coverage. C.  The bands/frequencies chosen allow 20 MHz bandwidth. D.  State Parks is using 2.4 GHz on the Island and we didn't want to interfere. Questions may be directed to N7IE at the QRZ.com e-mail address.  .. .
