2 el 28MHz LFA2 Yagi (1.4m)
A 2 element 28.0-28.6MHz LFA2 (bent reflector) Yagi
The G0KSC LFA Yagi represents a major step forward in the development of the Yagi Antenna, it provides a low-noise front-end for your radio so you hear more weak signals while at the same time maximising all round performance. Hard to beat with a direct 50 Ohm feedpoint and no matching losses and suppression of unwanted noise !! More information on the LFA Yagi can be found here.
This 2 element LFA is an excellent option if you do not have space, especially stacked !! 2 at just 5m spacing provide 14.6dBi (when placed 10m above ground) and around 28dB F/B!!
NOTE: With All our HF antennas we can custom design your element taper and element size requirements in order to cater for all weather and installation requirements Email us for details.

This antenna is made 5/8 inch (15.88mm) centre elements and 1/2 inch (12.77mm) outer elements with the end sections 3/8 inch (9.525mm). The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which will support 2 inch (50mm) masts. Boom is 1.5 inch square (38.1mm) 16SWG aluminum.

Our antennas are constructed with the best quality materials in order the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.2mm of what they should be, this ensures they work as well as our software model predicts.
Note: much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the make up or our antennas have least effect on performance and pattern degradation. More information can be found here
