  • SIGMA EURO-COMM DELTA – 40 HP Multi Band Full Wave Loop

The Sigma Euro-Comm DELTA- 40 HP


Multi Band Full Wave Loop Antenna Wire Antenna


 The DELTA-40HP is a full wave loop designed to operate on

40m (7MHz), 15m (21MHz) and 10m (28MHz) without an ATU and other bands with an

ATU.


There is a 4:1 balun at the

feedpoint enabling it to be fed directly with 50ohm 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 postion.


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

vertical


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.
