VERSA Beam KA1-405 (40/30m - 2elements, 20-10m - 5elements, 6m - 8elements)
This is quite new antenna VERSA Beam KA1 which was developped by Kohjinsha Co.,Ltd.
VERSA Beam can cover 8 ham bands (40m, 30m, 20m, 17m, 15m, 12m, 10m & 6m) by one antenna.
All frequencies are adjusted by motor drive copper elements with digital control in order to get the best performance.
Excepting 40m band, the antenna works as a full size YAGI beam. 40m band is performed with center loading coil equipped into AEU (Adjustable Element Unit). It enables to shorten approximately 30% length of element. This is new technology of adjustable beam antenna in the world.
This antenna is great product which took 2 years development period to enable the best performance of adjustable beam antenna system by JH1ECG and their group.
Special New Feature:
When the "Home button" is pressed , all elements start to retract to AEU. Once each element (1. Ra, 2. Ref, 3. D1, 4. D2, 5. D3) is completed retraction, the number of element will be indicated separately on display in turn using sensor. This feature can find visually by controller unit whether or not each element is working correctly. User will be able to know malfunction of antenna system easily. Then, it will shorten the time and cost in order to repair and/or replace defective AEU.
Frequency Range : 7Mhz - 50Mhz
Number of elements: 7/10Mhz - 2, 14 - 28Mhz - 5, 50Mhz - 8
Power Rating: 7Mhz - 5kW SSB, 10 to 50Mhz - 5kW CW
Longest Elements (m): 14.8
Boom Length (m): 10.0
Turning Radius (m): 7.9
Weight (kg): 63
The construction has executed on July 12, 2014. Thanks for cooperation by JH1ECG, AH7C, JH1BUO, JE1GGI, JF1UMK & JN1NDY.
