The Sigma Euro-Comm DELTA- 10 HP
Full Wave Loop Antenna Wire Antenna
The DELTA-10HP is a full wave loop designed to operate on 10m (28MHz) without an ATU and other bands with an
There is a 4:1 balun at the
feedpoint enabling it to be fed directly with 50 ohm coax – RG-213 or Mini 8 is
probably the best but other variations of coax may
be used so long as they are
of a 50ohm impedance.
The loop comes complete with three insulators to provide
anchor points. It may be mounted flat
(horizontal) or raised to a vertical or near vertical position.
It may be configured as either a square loop
(Quad) or equilateral triangle (Delta).
FULL WAVE DELTA LOOP.
Configured as a delta loop or equilateral triangle, if laid flat will be
good for near DX. If vertical, or near
will provide low angle radiation which is good for long range DX in
the direction of the loop (looking straight on at the front) and near DX off
the sides. Gain 3.2dBd.
FULL WAVE QUAD LOOP If laid horizontally will be good for
NVIS, if vertical 2.8dBd gain. Sloping
at 45 degrees will provide low angle DX.
