A discone antenna works very well with this receiver, particularly the ones
with a whip above the cone. It will give adequate performance from medium
wave frequencies through to UHF. You may get some breakthrough on some VHF
frequencies if you live near to a powerful pager transmitter. A directional
antenna and rotator can be used to overcome this sort of interference but
with much greater cost and complexity.

Try the discone and see how you get on. Get the discone up as high as
possible on a mast attached to a chimney above the house perhaps, or on an
aluminium pole out in the garden. Try to route the cable by as direct a
route as possible to the receiver. Make sure the cables and connectors are
of good quality and that all joints outside are completely covered with self
amalgamating rubber tape with a layer of insulating tape over the top. Use
loctite or similar thread locking compound on the discone elements to stop
them coming unscrewed due to wind vibration. This setup should last you
several years without giving any problems.
