A mobile phone base-station is on a 11 m high mast which stands on top of a hill of height 32 m above sea-level at a location that is 1.1 km inland from the shore. The terrain is dry sand and scrub. A yachtsman out at sea uses a mobile phone to communicate with the base-station on a 3 GHz carrier frequency. His phone has an external antenna attached to the top of the yacht's mast, 11 m above sea-level.

![A mobile phone base-station is on a 11 m high
mast which stands on top of a hill of height 32
m above sea-level at a location that is 1.1 km
inland from the shore. The terrain is dry sand
and scrub. A yachtsman out at sea uses a
mobile phone to communicate with the
base-station on a 3 GHz carrier frequency. His
phone has an external antenna attached to the
top of the yacht's mast, 11 m above sea-level.
Neglecting any refraction in the atmosphere, at
what distance from the base station would the
first (i.e. the furthest) of these nulls be
expected?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F02bff729-5ac4-4235-9c2a-e7aa3edc94ff%2Fc7e115d8-c81c-4acb-ae7b-a917d328b95b%2Fw0x51gr_processed.jpeg&w=3840&q=75)
