4 Antenna Mounting
4.1 TX Antenna
Omni antenna to be installed on tower or roof top construction as defined in site specific
construction drawing. As a general rule on any monopole installations the TX antenna shall be
attached to a 6 foot side arm mount, minimum distance away from the monopole unless the
antenna extends above the monopole in its entirety. Likewise the antenna shall be kept a
minimum distance of 6 feet from any other vertical structures on other types of towers. For
roof tip installations, the TX antenna must extend above all parapet walls and penthouses on
the roof top.
This radio transmitter (FCC ID: A4P-100-0007-01) has been approved by FCC to operate
with the antenna types listed below with the maximum permissible gain and required
antenna impedance for each antenna type indicated. Antenna types not included in this
list, having a gain greater than the maximum gain indicated for that type, are strictly
prohibited for use with this device.
This radio transmitter may only operate using a vertically polarized antenna with maximum gain
of +8 dBi. To reduce potential radio interference to other users, the antenna gain should be so
chosen that the effective radiated power (ERP) does not exceed 30 Watts.
Antenna Type: Monopole
Polarization: Vertical
Maximum Gain: +8 dBi (maximum gain of antenna + cable loss is 0dBd)
Following is a list of the possible antennas and antenna cables combinations.
