    Product Description

    Comba Critical Point RXUHFA36DC1WB DC powered Class A, duplexed single sub-band UHF BDA available with either 2.5MHz passband between 470 and 512MHz or 2.5MHz from 450MHz to 470MHz.

Narrow band filters are 32, max. Also supported are uplink channelized squelch and ALC (Auto Level control). Low noise is brought about by PA uplink shutdown for the base station while inbuilt BDA oscillation prevention is guaranteed by a compulsory isolation test. SNMP is support for intelligent web-based GUI configuration.

    Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Please check outside signal level in decibels before ordering. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

    If it is too weak, submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

    Please note: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
