6 FO22 yagis (two views) with polarity rotation originally
built by K1FO as part of his 12 FO22 yagi array. This array was used for many
successfull EME contacts on 70CM (432 Mhz). |
|
Notice the polarity rotor on the aluminium "I"
beam above the counterweights to offset the array. First chance to see how
polarity rotation doubles the effectiveness of the array. |
|
12 foot diameter TVRO dish with VE4MA feed horn on 23CM
(1296 Mhz) in early 90's. F/D .375 Dish was mounted on thirty foot tower. About
50 initial contacts were made with 300 watts in the shack. Dish was also
effective for tropo and Oscar 13. |
|
18 foot diameter homebrew dish built by N2IQU in 3 weeks
(KU4F design) .45 F/D used for 18 months on 23 cm EME. VE4MA feed horn.
Currently QRV at K2DH QTH. |
|
28 foot diameter Kennedy dish (two views) used on 70 cm and
23 cm EME. Both a W2IMU feedhorn and switchable dual dipoles for 70 cm were
used. |
|
Azimuth rotor was a surplus radar rotor and elevation by
hydraulic ram. A very fine antenna used until 1995 |
|
48 foot diameter dish (two views) built/refurbished from
government surplus (see QST May '96) in 1995 by N2IQU. F/D .41 |
|
W2IMU feed for 23 cm and switchable dipoles for 70 cm. This
is the current antenna used at N2IQU's EME station near Syracuse, New York.
|
|
15 foot diameter dish (SA) for use on X band (10 Ghz) EME.
Steerable but not QRV yet. N2IQU hopes to be QRV in the summer of "99 on
10 Ghz. |

THE ONE THAT GOT AWAY...60 footer Kennedy...with a very
interesting past. Luckily the 48 footer came along before I went way over
board. |
