41 Metres 7.1 to 7.3 MHZ<br />

31 Metres 9.5 to 9.775 MHZ<br />

25 Metros 11.7 to 11.975 MHZ<br />

19 Metres 15.1 to 15.45 MHZ<br />

16 Metres 17.7 to 17.9 MHZ<br />

13 Metres 21.45 to 21.75 MHZ<br />

11 Metres 25.6 to 26.1 MHZ<br />

Of course, what was stated earlier about propagation conditions<br />

on the amateur bands also pertains to the broadcast bands. Thus the<br />

49, 41, 31, 25 and 19 Metre bands will provide the most consistent<br />

results. 16, 13 and 11 Metres will be far more influenced by prevailing<br />

conditions. <strong>The</strong> four lowest frequency bands are not as popular as the<br />

others, particularly if one is using a fairly simple receiver. <strong>The</strong> only<br />

one of these bands that is likely to give good results is the 60 Metre<br />

band.<br />

Aerials<br />

Apart from the two sets that are intended for use with an integral<br />

telescopic aerial, all the receivers described in this book are designed for<br />

use with a longwite aerial. Such an aerial is merely an insulated wire<br />

that is as long as can be accommodated and positioned as high up as<br />

possible. <strong>The</strong> aerial should preferably be set up well clear of buildings<br />

or other large obstructions. It should also be well insulated from the<br />

ground as otherwise some of the signals generated in it will be drained<br />

away straight to earth, rather than to earth through the receiver’s input<br />

coil. A typical method of fixing a longwire aerial is shown in Fig.2.<br />
