A masterpiece of satellite technology – a unique Ku band feedhorn and 
mechanical polariser: ORIGINAL Seavey ESR-120-2 Broadband (10,7-12,75 GHz).

Condition: BRAND NEW – never used or installed, imported directly from 
American manufacturer.

Certificate of authenticity and of broadband tuning attached (details below).

Exceptional piece of equipment, intended  for the most demanding professional 
applications – a unique opportunity for the connoisseurs of DX and fringe 
receptions.

Built on the principle of famous and ground-breaking Seavey patent that 
revolutionised feedhorn engineering (see link below)

Features:
- intended for prime focus dish
- intended for LNBs with WR-75 flange – perfect match for Swedish Microwave 
LNBs
- intended for dishes with f/D = 0,35 – 0,42 (perfectly matches a shape of 
such a dish)
- intended for reception of linearly polarized signals
- unique BROADBAND CONSTRUCTION AND TUNING, performed on individual basis by 
the manufacturer at my special request: equal coverage of the FULL 10,7-12,75 
GHz frequency band (very unusal for Seavey feeds!)
- integrated design: feedhorn + mechanical polarizer, eliminating excessive 
VSWR and signal loss, usually encountered in systems comprising separate 
feedhorn and polarizer on the port between feedhorn and polarizer
- ultra-low VSWR = 1,3:1
- ultra-low insertion loss = 0,05 dB maximum
- patented probe design, taking into account the specific requirements of the 
f/D of the dish and increasing cross-polarity values
- high cross-polarity: 30 dB minimum
- patented waveguide design that enables increasing efficiency of the system
- overall efficiency of the feed = 77% @ f/D = 0,4
- low inertia, original Seavey 3-wire motor (5V, pulse, GND) that can be 
controlled with any standard receiver equipped with skew regulation
- original Seavey drawings with precise indication of the PHASE CENTER of the 
feedhorn, enabling ultra-precise positioning of the feedhorn in the focus of 
the dish
- certificate of authenticity with an indication of serial number of the 
feedhorn as well as with a stamp and signature of the responsible engineer
- the feedhorn’s WR-75 port is originally SEALED with a cover that creates 
a sterile environment in waveguides and thus prevents dust, dirt and humidity 
from getting inside – the cover has never been removed
- stored in a warm and dry place
- brand new and never used, so you don’t risk buying a worn-out item with a 
greasy or distorted probe and you have a full guarantee of the highest Seavey 
quality
- almost impossible to buy in Europe

In general: a brand new collector’s piece of truly professional equipment 
manufactured by the company renowned for peerless quality, durability and 
reliability as well as unrivalled knowledge and experience in satellite 
technology, accompanied with full documentation, enabling error-free 
installation.
