2m 144 9el2 Yagi from Vargarda Radio AB
Now anyone who has worked 2m Nordic Activity Contest with me, will know that this Yagi rocks. I don't really know what kind of Voodoo was used in addition to the damn good engineering of this antenna. For example, i am currently using 50 watts rom the FT-897 with an antenna elevation of about 20 meters. I am easily making contact in southern Sweden, Norway and at time the North cost of Poland. This is with 1 9 element yagi. My plans are to stack 2-4 of these yagis in the coming years, and to compliment the stacking with an even better mast head amplifier. Currently I use the MHP-145 which is a super low-noise Mast-Preamplifier capable of handling RF-Power levels up to 1500 Watts in SSB. The heart of the system is the low noise preamplifier LNA 145, combined with two (2) High Power coaxial Relays in a weatherproof enclosure.I think that the LNA 145 is one of the best 2-m preamplifiers available today. It features a super low noise figure of 0.4 dB, a high 3rd order Intercept Point (+ 22 dBm) and a supherb selectivity thanks to a high-Q tunable bandpassfilter at the output.
The coaxial-relays have been tested up to 2 KW SSB, they feature large goldplated contact areas and an extremely low insertion loss. The manufacturing is done with double shielded Teflon coaxial cable in order to guarantee a low losses and a high power handling capability.There is no RF-VOX and protection circuits in the MHP 145, because Vox circuits will not work propperly at power levels above 1 KW.Back to my 9EL2 yagi. The company which makes it is a Swedish company and truthfully, I dont normally care about marketing for companies earning money for something i paid for. I just cant tell you how awesome this yagi is. 1 Yagi, good cable and even better connectors insure that I am a top low power station each adn every time during NAC.
