    I agree and waveguide is a dangerous emitter of rays if it gets damaged or even pinholed. There are problems to be overcome such as curvature of the earth and the true height and distance of the target. Air temperature vis -a-vis ground temperature has an effect on range. Overall some form of air patrol and/or a good ESM, ECM, and ECCM systems fitted aboard ship, will always be useful and give one's ship more freedom of action.

    Cannot the signal be TX'd to the ship thus avoiding the coax.

    As far as I am aware, the system currently being worked on will use a Simrad 4G radar with an ethernet output that connects to ship via wifi.
    There are always going to be trade-offs between range, weight and power requirements but that is what they are starting with.

    a New horizon for Simrad yacht radars with a jump from 200feet low range in harbour to 36nm max range . Will the info be available to everybody with a similar receiver? Cheap at 1995USD but poor definition of targets especially land features. It seems to me this is exploratory technology , untried in an extreme marine naval environment.

    Since the kite is effing big as it is pulling the ship, this is probably not an issue.

    Not with that dinky radar, no. I imagined something a bit more substantial.
