We are restructuring!

We are pleased to inform you that we have merged with another local supplier, Push To Talk South Africa (Pty) Ltd [PTT SA].

We negotiated this restructuring venture in order to add additional support and two way radio communication equipment to our existing product portfolio available to all DRS customers.

The commercial radio band is mainly divided into VHF (Very High Frequency [longer wave lengths, longer distance]) and UHF (Ultra High Frequency [shorter wave lengths, shorter distance]), but if you’re buying your very first two way radio, these terms are probably more confusing than helpful.

We could probably simplify things by stating that VHF is usually suitable for any scenario where line-of-sight is possible (outdoor, no obstructions), whereas UHF works well indoors and between buildings; and although we wouldn’t exactly be wrong, we do recommend National Instruments’ RF tutorial as additional reading material for you.
