The Flann Dual Polarized Horn, Model DP241 – AB, is a multi-octave, coaxially fed, quadridged horn suitable for many applications requiring a high performance over a broad band. The standard antenna covers the frequency range 18 GHz – 40 GHz and offers high isolation with low phase and amplitude imbalance between ports. Other frequency options are available within the 6 GHz to 50 GHz band.

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

The horn maintains a low VSWR while the precision machined construction ensures very low cross polarization levels.

Special Dual Polarized Horns are also available operating up to 50 GHz using 2.4 connectors.

The standard DP241-AB will function down to 6 GHz with a reduced performance.
