Dipole ArraysLBLAD-600

Lindenblad dipole array, FM broadcast

Description

The S.LBLAD array is designed for mixed polarisation broadcast on FM radio systems. The array consists of four folded dipoles affixed to a rugged mounting bracket, fed in phase from a machined power splitter, to achieve an omnidirectional mixed polarisation antenna. The arrays give a maximum gain of 0.5dBd. The balun assembly is completely encapsulated in poyurethane resin, totally preventing moisture ingress. The power splitter / array input is terminated standard with an ‘N’ type female.
