*DX NEWS* 2DA357 Dave Celebrates NY with NEW LFA Yagi

Dx Adventure Radio Club (DA-RC) member 2DA357 Dave is delighted with his new 4 element GOKSC LFA Yagi for 10 and 11m which now towers above his home in the USA.

Made by UK based company InnovAntennas and adjustable from 26.5 – 27.5 MHz to suit user’s preference, this antenna provides a low-noise front-end for your radio so you hear more weak signals, while at the same time maximising all round performance.

At just £299.95 – less 20% for outside EU buyers like Dave – and arriving from the UK in just 7 days, no wonder he’s excited with his brand new toy!

Characterised by a rectangular shaped, full wave loop driven element that is laid flat on the boom between and in-line with the parasitic elements, the LFA (Loop Fed Array) Low-Noise Yagi is very different from the traditional dipole fed Yagi in many ways with its primary benefit being unwanted noise rejection.

Dave has kindly taken some pictures during the assembly and installation of his new antenna project to share with his fellow members and others whom might be interested in a unique style of yagi.

1.  See Above & Right: In the workshop at home, everything is pre-drilled and square to the 5.45 meter boom which is made of 1.5 inch (38.1 mm) square 16 SWG aluminium.

2.  See Left: The yagi is pre-assembled on the ground in my backyard with the support of two plastic saw-horses in preparation for the erection.

(See https://www.delta-alfa.com/antenna-solutions/ for more infos on this method).

3.  See Right:  The junction of PL-259  connector plugs and coaxial cable is secured with black silicone tape to protect it from water or condensation.

4. See Left:  Using a DAIWA SWR & POWER METER model CN-801HP3, the SWR is found to be below 1.5:1 from 27.000 MHz to 27.700 MHz.

5. See Top Right:  Almost there…the new 4 element GOKSC LFA Yagi is fitted to the telescopic mast beneath my vertical antenna, guys wires hanging loosely, with the rotator beneath.  A timber pale and step ladder are used to support the mast until it is elevated into position.  Care is taken with the nearby overhead power lines.

6. See Right: With the new yagi now at 45 feet in the air, my first contact is with Andy 101AT170 in Papua New Guinea at 5/8.  Next is 133SD156 Allan in the Northern Marianas islands at 5/7, followed by 302SD200 Slava on Sakhalin Island at 5/7.
