Hi Mike,

I occassionally seem to be getting some viewsheds with zero visible percentage.

I've checked that the transmitter (which is set at a height above sea level) is above the ground height in the area.

Any easy potential points for error i should look at?

Thanks

Andy

    Andy,

    What are you using for the receiver height? I would expect some visible coverage if your transmitter is above the ground unless your receiver would always be blocked for some reason.

    Thanks,
