What type of radio aerial do I need?

To access most radio servicesyou need an aerial. These can vary between built-in, indoor and external and they are different depending on theplatform. This guide gives a simple overview of the different aerials available.


FM Radio

The most common FM radio aerial on a portable radio is a telescopic one. To get the best reception extend the aerial fully and move the aerial and radio around until you get the best reception. If using a hi-fi with a wire aerial, again extend as much as possible to get the best signal.

External aerials are also available for FM radio and will significantlyimprove reception.The aerial and cables need to be well maintained and you will need a radio that has an option to connect an external aerial.

AM Radio

A radio which can tune to medium and long wave services usually hasan aerial built in, whichyou cannot see. As the aerial is directional, by simply turning the radio you will be able to get the best reception. AM does not use the telescopic aerial.

Some hi-fi’s have external AM aerials that tend to look like many wires wound around a plastic loop. This needs to be rotated to find the best signal.

DAB radio

You need to have a suitable DAB aerial to receive DAB services.Portable DAB radios will usually have a telescopicone,but if you are retro-fitting a DAB radio into a car, you may need to add a DAB aerial.

External aerials are also available for DAB and will significantlyimprove reception.The aerial and cables need to be well maintained and you need a radio with the option to connect an external aerial.Unlike the other services, all the predictions of DAB coverage are for indoor coverage.
