JK Antennas Donates 40-Meter Yagi to

JK Antennas of Connecticut has generously donated and assembled a new
two-element, 40-meter Yagi on site at Maxim Memorial Station W1AW at ARRL
Headquarters. JK Antennas’ Ken Garg, W3JK, and his assistant Craig Finley
transported the new Yagi to W1AW on April 24 for assembly and

“I am very grateful for Ken’s generosity,” said W1AW Station Manager
Joe Carcia, NJ1Q. “His kindness toward W1AW, his technical expertise, and
pride in his product is most refreshing.”

Carcia said
the new antenna replaces an antenna that had not been performing as needed
and had failed a couple of times in the past.

“What we
did on April 24 was remove the old two-element, 40-meter Yagi — fixed to the
south-southwest and used for all of our 40-meter code practice and
bulletin transmissions — and replaced it with the JK402T two-element, 40 meter
Yagi,” Carcia explained.

The new 40-meter Yagi is installed at W1AW.

Taking down the old antenna were Andrew Toth — who
works with antenna pro Matt Strelow, KC1XX (XX Towers Inc.) — and Finley.
Carcia pitched in to tram the old antenna down a line and off the tower.
Strelow and Toth, who handle most of W1AW’s antenna maintenance, were at
W1AW to perform spring antenna and tower inspections. “The installation of the
JK402T was a bonus! The timing just worked out,” Carcia said, adding that
the pair also installed a second 6-meter loop for scheduled transmissions
on that band.

Strelow, Carcia, and Finley hoisted the
new antenna into place with Toth pulling from the tower and then affixing the
new Yagi and making the necessary feed-line connections. Garg oversaw the
process of assembling the antenna and trimming the elements to W1AW’s

Carcia recounted that the old antenna could
not provide full band coverage right out of the box, and required the user
to pick a band segment for operation. “I had to compromise and tune it for
the CW/digital segment,” Carcia said, but when it came to either end of 40
meters, the amplifier was not happy.”

In contrast,
Carcia said the JK402T offers wide bandwidth, keeping the SWR below 2:1 across
the entire 40-meter band.

The entire enterprise
