LFA Antenna 2 Elements YO2MBU



The 40m band has also the magic durring this time of the year, inspired by the G0KSC, I took the decision to design  and test the LFA antenna for the 40m. This antenna was installed in my attic at 15m high, and was made from copper flexywire 3mm. The fact the LFA loop are feeded with 1:1 balun realised by YO2MLL. 

 

 The antenna has one loop and one reflector.


 

 The SWR  is low with nice value of gain.


This antenna has 10 dBi Gain and just 14 dB F/B.
