VistaMax OBR3650HP Professional Installation Guide

Purpose:

The purpose of this guide is to instruct the professional installer on how to set the

transmit power on the OBR3650HP to ensure FCC EIRP limits for the 3.65GHz band is

not exceeded.

General:

Only qualified personnel should be allowed to install, replace, and service the equipment.

The device cannot be sold retail, to the general public or by mail order. It must be sold to

dealers.

Installation must be controlled.

Installation must be performed by licensed professionals.

Installation requires special training

The VistaMAX radio and antenna should be installed ONLY by experienced installation

professionals who are familiar with local building and safety codes and, wherever

applicable, are licensed by the appropriate government regulatory authorities. Failure to

do so may void Vecima’s product warranty and may expose the end user or the

service provider to legal and financial liabilities. Vecima and its resellers or distributors

are not liable for injury, damage or violation of regulations associated with the

installation of outdoor units or antennas

FCC EIRP:

The allowed EIRP for 3.5MHz bandwidth is 3.5watts or 35.4dBm

The allowed EIRP for 7.0MHz bandwidth is 7.0watts or 38.5dBm

Power Adjustment on OBR3650HP:

Transmit power of the OBR3650HP is adjusted in 0.5dB steps via the Web Browser

interface. Vecima has provided head room in the OBR transmitter to allow the

professional installer to use different RF cable types and lengths.

Installation Scenarios:

Vecima OBT3650HP consists of the following items:

1 – OBR3650HP + mounting accessories and PoE surge suppressor.

Adjusting the power of VistaMax OBR3650HP 7.0MHz bandwidth The transmit power can be adjusted by 0.5dB steps. Enter the new power setting in the right hand field then click on the “Submit” button as per the above screen shot.
PAGE 4
To apply the new power setting, the OBR needs to be rebooted under the “Apply Configuration” screen, see above screen shot.
PAGE 5
The above screen shot shows the new transmit power now set to 26.5dBm.

The above screen shot shows the new transmit power now set to 23.
PAGE 10
Omni Antenna: Since the Omni antenna is 1dB lower in gain then the transmit power of the OBR can increased by 1dB. The diagram below is shows the gains and losses in the RF chain for the calculated EIRP of 37.5dBm. OBR3650HP 7.0MHz Tx Power Adjusted to 27.0dBm EIRP = 37.5dBm 11dBi Omni Antenna 5-ft 1/2" Coxial Cable Loss = 0.
PAGE 11
Adjusting the power of an installed evaluation kit for 7.0MHz bandwidth The maximum transmit power of the OBR3650HP can be used when using the 11dBi Omni antenna. If a shorter RF cable is used, then the transmit power will need to be adjusted down.
