Re: antenna tuner for uBitx

The type of antenna tuner depends on the type of antenna.  L-network for end-fed
or high impedance antennas.  T-network for medium to low impedance antenna.
Pi-network for dipoles.  It is unfortunate that specifications for ATU's usually do not
include the adjustable impedance range for each band that they cover.

Impedance matching is important if one wishes to deliver all TX power to the antenna and prevent  final stage to be overheated due to standing waves reflected from the mismatched antenna (load).
Matching the antenna also improves the ability of the RX to receive all the weak signals and nothing is wasted as heat.
