DISCONTINUED INNOV Delta C-140 - 40m Rotating Dipole

The DELTA C-140 is a rugged 40m rotating dipole

It covers the whole 40m band without an ATU with an SWR of less than 2:1 from 7.0MHz to 7.3MHz and better than 1.6:1 from 7.0MHz to 7.2MHz, this is not a characteristic that most ‘short’ dipoles provide. Next is the combination of capacity and coil loading.

Combined the use of high-efficient, wide-spaced coils and capacity loading to produce a 12m wide 40M rotating dipole with a radiating efficiency of just over 89% along with all-band coverage without the need for an ATU.

The capacity loading has allowed for the coils to be moved further out along the element lengths to improve efficiency and bandwidth and the solid structure with fast taper ensures no guying is needed as the antenna can fully support its own weight.

This Antenna is Seriously HD. Centre dipole section is 55mm (almost 2''1/4) Diameter with 2mm wall and the antenna has a fast taper to the end sections which are still a full 25mm (1'') diameter where the capacity loading is.
