BANDSPRINGER MIDI 10m-60m
A multi-band long-wire antenna from SOTABEAMS
General information
The current generation of HF portable radios offer great
performance on the HF bands—but to get the best out of them,
an efficient antenna is required. The Bandspringer is a multi-
band long-wire antenna. The length has been chosen to
ensure that it will work with the internal antenna tuners in
portable radios such as the K1*, KX1, K2 and KX3. It will also
work well with the Elecraft T1 auto-tuner and the MFJ portable
tuner.
*Note that the Bandspringer must be used with an antenna tuner—it is not suitable for
connection directly to an FT817 or similar radio without a tuner.
Suitable tuners will usually be advertised as being able to tune a random wire / long wire
antenna. Some tuners state in the small print that additional equipment is required for this,
please check your tuner manual for details. For example, it might say "Optional external
Balun allows tuning of random length, long wire or ladder line fed antennas", indicating that
the tuner is likely to need a 4:1 balun connected between it and the Bandspringer.
The exact range of bands may vary depending on your tuner. The Bandspringer Midi should
work on 40m, 30m and 20m with any tuner capable of tuning a random wire / long wire
antenna. It will work effectively on all bands from 60-10m with most such tuners, but not
necessarily all.
*NOTE: The internal tuner on the K1 has a limited matching range on 80m and coverage of
this band may not be possible without using an external tuner.
