The antenna feed may refer to all components connecting the antenna to the transmitter or receiver, such as an impedance matching network in addition to the transmission line.

And the view certainly is fantastic - you know, all the times I've been to Arecibo, I've never made it up here to the antenna feed.

For fine attitude control, the S-band antenna feed is mounted slightly off-axis.

Secondary Scan: A scanning technique where the antenna feed is moved to produce a scanning beam, examples include conical scan, unidirectional sector scan, lobe switching, etc.

The 8.8 m diameter parabolic antenna, using a Cassegrain antenna feed, had a 0.4 beamwidth and a gain of 51 dB.

Another was gently manipulating a squealing broadband scanner hooked to an antenna feed.

We found one antenna feed.

The P-15 uses two open frame elliptical parabolic antenna accomplishing both transmission and reception, each antenna being fed by a single antenna feed.

The radar uses an open frame truncated parabolic antenna with a stacked antenna feed.

In measuring the impedance or radiation pattern of a balanced antenna using a coaxial cable, it is important to place a balun between the cable and the antenna feed.
