SOTABEAMS BANDSPRINGER MIDI Instructions

BANDSPRINGER MIDI 10m-60m
A multi-band long-wire antenna from SOTABEAMS
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 carefully 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.
What do you get?
The Bandspringer consists of two wire elements, both are made of high quality tinned copper wire,
insulated with a yellow PVC coating. This wire type has proved a good compromise between flexibility and
performance. The yellow insulating jacket makes it easy to spot on most surfaces (not snow of course!)
which makes handling much easier. The elements are 42ft each. The wire elements are supplied wound
on a Wire Winder to make deployment and recovery in the field as easy as possible.
Each element is terminated in a good quality "Banana" plug. The radiating element has a braided nylon
cord extension to make it easy to use. The extension is firmly attached to the wire at one end and has a
pegging loop at the other end.
An adapter is provided with a BNC plug and banana sockets to allow the antenna to be connected to your
radio or tuner. We stock a BNC socket to UHF plug adapter which can be purchased separately if your
equipment has an SO239/UHF socket.
The Bandspringer is supplied with two high-quality aluminium alloy pegs and two insulators (see overleaf
for instructions)
The total weight is approximately 327gm (11.5 oz.).
*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.
