Ku Band Feed Horn

Ku Band Scalar Ring

Scalar Ring increase week signal on Ku Band dish antenna.Its very Scalar Ring effective when you have signal on bottom point.

Illuminate signal from dish edge


Scalar Ring provide an excellent method for feeding parabolic reflector antennas.Parabolic reflectors need another antenna to “illuminated” the reflector element of the antenna and the Scalar Ring provides a very convenient method of achieving this.In this application the horn antenna is known as a ‘feed horn’ in and it can be designed to provide sufficient directivity to illuminate the reflector sufficientlyevenly without too much spillage over the edge of the dish. The use of the Scalar Ring also minimizes the spurious responses of the parabolic reflector antennato signals that are not in the main lobe.

Prime focus feed Horn

Ku Band Prime focus feed horn for C-Band Dish

Our High Efficiency Ku Band Feed Horn has been developed to provide superior performance by increasing the efficiency on C-Band dish reflector illumination. Our Adjustable scalar of feedhorn an improvement of 15 to 20% gain. The adjustable Scalar works by increasing the gain on dish antenna to illuminate reflector surface more efficiently, concentrating more Ku band signal into the LNB input.


Use any existing Ku band Lnb Single Twin, Quad.
f/d ratio adjust according to your C-band Dish antenna depth.
f/d ratio range .35 to .5
Use Inverto Black Ultra Lnb for extra Hi-Gain
