The SLx Gold digiTop aerial is a high performance adjustable log periodic indoor TV/Radio aerial. The aerial is powered with a 12V DC power supply (which is supplied), there is a built in amplifier and the gain is adjustable. The SLx Gold digiTop is fine for both analogue and digital TV and radio signals, so it will work with Freeview and DAB Digital Radio as well as analogue TV and radio. The aerial elements are fully adjustable and the RF IN/OUT sockets will convert the aerial into a signal booster.
This version of the digiTop includes a 4G filter, so the frequency range is lower (see below). If you live very close to a mobile phone mast you may need this version rather than the Original SLx Gold digiTop 27769R.
