Additional information regarding Onwa Radar
KR4001 120cm Open Array
KR3001 180cm Open Array
Onwa Radar is manufactured with the Professional user in mind. Check the specification and you will see that it out-performs many radar sets produced for the leisure market. Of particular merit are the figures for beam width, think of beam-width as focus of the radar beam; something Onwa radars are particularly good at achieving. KR-1007 is just 4 degrees horizontal beam-width and 25 degrees vertical. The Open Arrays are even better, 120cm Open Array being just 1.9 degrees and the 180 cm Open Array an incredible 1.2 degrees.
Onwa KR-1007 34nm 4kW X-Band Radome. The Radome is quite large at 60 cm and this is because it is designed with the professional user in mind and has a large antenna within the dome to achieve a horizontal beam-width of just 4 degrees – compare this to other make radar designed for the leisure industry. However at 60 cm it is possibly more suitable for a power vessel and may be too large and heavy to consider mounting on the mast of a sailor. For a sailing boat consider mounting on a 10 foot pole on a stern quarter- this is where I have mine mounted and it works really well.
