AI Overview
Ofcom issues three main types of Restricted Service Licences (RSLs): Short-term RSLs (S-RSLs),
Long-term RSLs (L-RSLs), and Audio Distribution Systems RSLs (ADS-RSLs).
These licences are for radio services with limited coverage areas, often used for events or within specific establishments.

Short-term RSLs (S-RSLs): These are typically for short-duration broadcasts related to specific events or trial services.
They are usually limited to a small coverage area and a short period, such as 28 days.
Examples: Radio coverage for a sporting event, a religious festival, or a short-term trial of a new radio service.

Long-term RSLs (L-RSLs): These are granted for longer periods, often one to five years,
and are used for radio services at specific locations like hospitals, universities, or shopping centers.
They are typically broadcast on AM or FM frequencies.
Examples: Hospital radio, university radio, or a radio service broadcasting within a shopping center.


The main problem with Very small AM Antennas, Is the SWR going out with changes in the weather, rain etc
The poor efficiency dont matter, you just need to put more power in, to compensate for this
But its the Hi-Q that makes very small AM antennas, go off tune in bad weather
