Antény britského výrobce InnovAntennas (G0KSC) se pro své kvality stávají standardem pro nejnáročnější aplikace, jako jsou EME, závodní a DX superstanice.
InnovAntennas využívají pro návrh svých antén nejmodernější počítačové technologie ve spojení s metodami "Particle Swarm Optimisation" (považované za nejlepší optimalizační technologii současnosti).
Výsledkem jsou inovace nabízející nejvýkonější anténní systémy, které jsou v současné době k dispozici.
Exkluzivní návrhy špičkových anténnářů světa byly přetvořeny v profesionálně vyrobené mechanicky vynikající antény.
Vyrábí se několik variant každého modelu, aby se vyhovělo praktickým požadavkům komerčních i amatérských uživatelů.

A 4 element 28.0-28.6MHz LFA 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.
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 EmailThis e-mail address is being protected from spambots.

Specification
This antenna is made 5/8 inch (15.88mm) center elements and 1/2 inch (12.7mm) 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 16SWG aluminum.
OTHER TAPER SCHEDULES ARE AVAILABLE IN THIS ANTENNA, CALL OR EMAIL FOR DETAILS
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
•Marine grade Stainless Steel Fittings
•Original Stauff Insulation clamps
•Mill finished boom and elements for highest levels of accuracy
