| 11. | He used waveguides, horn antennas, dielectric lenses, various polarisers and even semiconductors at frequencies as high as 60 GHz;.

| 12. | The WHJM transmitter is located to the north in nearby Hogg horn antennas removed prior to WHJM's 2006 sign-on .)
|
| 13. | Bell Laboratory engineers designed a large horizontal conical horn antenna with a parabolic reflector at its mouth that re-directed the beam.
|
| 14. | The Dnepr involved the horn antenna being reduced from 20 to 14 metres in height and the addition of a polarising filter
|
| 15. | Tuba used a horn antenna built of mesh wire 150 feet long and driven through 22-by 6-inch waveguides, possibly the largest ever built.
|
| 16. | The "'Holmdel Horn Antenna "'is a large microwave horn antenna that was used as a radio telescope during the 1960s at Robert Wilson.

|
| 18. | The low gain horn antenna is located under the center of the probe because of an adapter that connected the probe to the launch vehicle.
|
| 19. | He invented a horn antenna and hit on the idea of using a hollow pipe as a feedline to feed radio waves to the antenna.
|
| 20. | A horn antenna or microwave horn is an antenna that consists of a flaring metal waveguide shaped like a UHF and microwave frequencies, above 300 MHz.
