LA4LN's antennas

The photo shows my home made, computer optimized, 7 band trap beam antenna for 40m (3 el.), 30m (3 el.), 20m (4 el.), 17m (1 el.), 15m (4 el.), 12m (1 el.) & 10m (4 el.). Also shown 5 el. for 6m and 9 el. for 2m, and collinear verticals for 2 m and 70 cm. A number of different wire antennas for 160m, 80m, and 60m; a 120 meter long Beverage receiving antenna; plus a 48 element array for 70 cm, are not easily visible. (And the total length of some 1 km ground counterpoise wires are not visible either).

KL7/LA4LN working QRP from Homer near Anchorage in July 2007

Here we see a photograph from my KL7/LA4LN QRP (low power) operation from Alaska in July 2007 using the Yaesu FT-817 transceiver with 5 watts transmitter power and the fully automatic Elecraft T1 antenna tuner (middle left) hooked up to my Bobtail Curtain antenna wire. The Miracle antenna tuner (far left) was used at some rare high impedance cases, when the Elecraft tuner wouldn't obtain a match. The Palm Radio Mini Paddle for telegraphy shines in the front. A fishing vessel is seen on the fiord in front of the glacier-laden mountains in the background under the light Arctic night sky. Western USA and Hawaii were contacted from here on telegraphy and telephony. The longest contact from here was with VK2AYD in Australia, a distance of some 12.000 km (some 7.500 US miles). He answered my CQ call and said I was the only station he could hear on the band. The story and photograph was published as the cover story of the publication QRZ DX of 8 August 2007.

LA4LN working handheld via the AO-51 satellite

This photo shows my handheld operation from a mountaintop at locator JO49UF via the AO-51 satellite on 9 August 2007, making contacts with RW3XL, RA3OE, and G8GMU. I am using the Yaesu FT-817 battery operated transceiver with 5 watts transmitter power and the Maldol AH-510R whip antenna (halfwave on 2 m and 2 x 5/8 wave on 70 cm). The Dell Latitude D610 lap-top PC is running the Orbitron satellite orbit prediction software by Sebastian Stoff.
