Grounding and Lightning Protection
Installers of CEL-FI QUATRA EVO are encouraged to follow the lightning protection guidelines
documented in the National Electrical Code (NEC) and NFPA 780, and/or local codes.
Donor Antennas
The QUATRA EVO is designed to be used with the following antennas.
1. LPDA-R Antenna
Model Number: A62-V44-201 https://nextivityinc.com/antennas/lpda-r-antenna/
Figure 31: LPDA-R Antenna
The CEL-FI LPDA-R Antenna offers a powerful 12 to 14 dBi gain (depending on operator
frequency) over 617–4000 MHz and is designed to reduce out of band noise, to improve SINR
and overall signal quality. Mounting is made simple with the included U-Bolts. This CEL-FI
product also features a 10K ohm resistor that enables the antenna connection to be validated
by CEL-FI NUs equipped with the antenna sensing capability.
• 12–14 dBi gain
• N-type(f) connector
• 5G-ready
• Narrow beamwidth to reduce noise
• Rugged construction for harsh environments
• Includes a 10K ohm resistor for special CEL-FI applications
