The Flann Dual Polarized Horn, Model DP240 is a multioctave, coaxially fed, quadridged horn suitable for many applications requiring a high performance over a broad band.

These high performance units covering the frequency range 2 GHz to 18 GHz offer high isolation with low phase and amplitude imbalance between ports. The horn maintains a low VSWR while the precision electroformed construction ensures very low cross polarization levels.

*SMA, K and 2.4mm connectors are not hermetically sealed. Therefore to achieve IP54 rating the mated cable connection must be adequately sealed.
