InnovAntennas continue to supply the World’s top DX’ers with large antenna systems with over 55% of sales being into the USA and 10% into Japan. Ray Higgins, W2RE purchased 4 x 6el LFA Yagis (9.5m booms) for 50MHz last year stacking them vertically on a 100′ fully rotating tower. Ray made these comments today on his remote ops installation.

SiX METERS!

The new 6M ARRAY in Eastport, Maine is working fantastic. Thanks to Justin Johnson from Innovative Antennas for modeling the array before we installed, we went with smaller boom (7EL) and closer stacking on his suggestion for this particular install and its paid off big time with us working UB7 well ahead of anyone else in the US antennas @ 100’/80’/60’/40′.

G0KSC Designed low noise Yagis are very popular for EME on VHF too due to their super-quiet properties.

7 element 50MHz LFA2 WOS Yagi (9.5m)

A 7 element low-noise LFA2 Yagi Bent Element Yagi

The 7LFA2WOS was originally designed for 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!

Specification

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.
