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, and can be stacked to achieve higher gain, a narrower beam or multiple transmissions. The balun assembly is completely encapsulated in epoxy resin, totally preventing moisture ingress, and has been tested to BS5490:IP67. The power splitter / array input is terminated standard with an ‘N’ type female, although cable and connector options are available upon request.
