InnovAntennas 50MHz 7element LFA-WOS
50 MHz 7-element G3WOS design Yagi
7-ele LFA-WOS 50MHz
Part Number : Z08564-0053
7 element low-noise LFA2 Yagi Bent Element Yagi
The 7LFA2WOS was originally designed for Chris G3WOS
The G0KSC LFA Yagi is 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. This 7 element 50Mhz LFA2 is another exciting slant on the LFA design with both the last third of both the reflector and first director elements being bent towards the driver loop in order to enhance performance. Incredible levels of F/B have been achieved providing the ultimate in rear-end suppression.
This antenna has very highly suppressed lobes in both azimuth and elevation plots and therefore is idea for very noisy city locations. If you want to beat the noise in a mid-sized 6m antenna, this is the one for you!

This antenna is made with tapered elements 5/8 inch (15.88mm) centres and 1/2 inch (12.7mm) outer sections. 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 1.75 inch square 10SWG (3.2mm thick) aluminum in the centre, tapering at the tips to 1.5 inch 16SWG (1.6mm wall) at the tips. A boom guy system is provided with this antenna.
Our antennas are constructed with the best quality materials in order that 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, ensuring 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 of our antennas have least effect on performance and pattern degradation. More information can be found here
