Broadband UHF 4 dipole array, aluminium, 400-520 MHz, 250W per input, quad N-type females, quad cable, 0 dBd per dipole - 3.4m

Product code: S4B44-X

The S4B44-X UHF dipole array antenna is a unique UHF 4-dipole vertical stack array antenna with quad inputs/outputs and cables which allows the use of multiple transmit or recieve functions within the UHF 400-520 MHz frequency range. The S4B44-X quad dipole array antenna comes standard terminated with 4 x N-type female connectors, but can be altered to suit your requirements, for low PIM requirements please request 7/16" DIN or 4.3-10 connectors. ZCG recommend mounting the S4B44-X UHF dipole array antenna as high on your structure or tower as possible using 2 x UAM180L or 2 x UAM90L in either a top-bottom or bottom-bottom configuration.
