1. An antenna apparatus for detecting a leaked electromagnetic signal, the apparatus comprising:
- a telescoping antenna;
a casing including a first casing portion and a second casing portion, a portion of the antenna being mounted in the first casing portion, the antenna being telescopically moveably relative to the first casing portion between a substantially extended configuration, in which the antenna extends away from the first casing portion, and a substantially retracted configuration, in which the antenna is substantially housed in the first casing portion;
a signal analyzer disposed in the second casing portion, the signal analyzer being connected to the telescoping antenna, the electromagnetic signal being detected by the antenna and analyzed by the signal analyzer.

Abstract
An antenna apparatus for detecting a leaked electromagnetic signal is provided. The apparatus includes a telescoping antenna and a casing, which has a portion of the antenna mounted in it. The antenna can move telescopically relative to the casing between an extended configuration, in which the antenna extends away from the casing, and a retracted configuration, in which the antenna is housed in the casing. A signal analyzer is located in the casing and is connected to the telescoping antenna. The antenna detects the electromagnetic signal, which is analyzed by the signal analyzer.
