2 Subscriber Installation Detail
Installation at the subscriber’s site is very simple – one small outdoor unit (the transceiver) and one
cable modem indoors. Power for the outdoor unit is carried over the TV-type coaxial cable between
the two units.
Frequency of operation, RF power, etc. are all determined automatically. There are no settings to
be made on site, with very few exceptions, which are discussed in this Section.

2.1 Transceiver
The Subscriber Transceiver contains a transmitter, a receiver and the antenna, all in one integrated
weatherized unit that is about 1x1 foot square.
2.1.1 Mounting
Mount the Subscriber Transceiver on a vertical pipe with at least 12 inches clear of any hardware or
other impediments. The mounting brackets will accommodate pipe outside diameter from 1.25 to 2
inches. The front face of the antenna must point in the direction of the system base station and
have a clear view of the Hub Transceiver antenna

.
Up-tilt or down-tilt is accomplished by loosening the cap screws on the sides of the mounting
assembly, as in Figures 2-2 & 2-3. Do not over tighten the mounting bolts or the up/down tilt cap
screws. The F-type connector must be waterproofed after installation, to keep out moisture. This is
typically done with electrical tape.

Subscriber installations located close to the base station installation may work successfully through tree
foliage, so called “near line of sight”, but this must be verified in the field. A rule of thumb for the loss through
deciduous foliage is 0.15 dB / ft in the UNII band.
