7 element Low Noise, High Gain Directional Loop Array (LFA-Q)
TheG0KSCLFA-Qpossesses all of the design traitsInnovAntennashave become well-known for. Direct50 Ohmimpedance (and hence no matching loss or pattern distortion), Minimal side lobes, High levels of Front to Back ratio (F/B) and Front to Rear ratio (F/R), and wide, flat bandwidth. However, theLFA-Qstands out for two more major benefits. High levels of forward gain and it's extremely rugged design which make it ideal for installation where harsh weather conditions are commonplace.
If you want the absolute best performance from minimal boom length and require performance that is available in any weather conditions or simply want something a little different, then theLFA-Qcould be the one for you!

This antenna is made with tapered elements 1/2 inch(12.7mm) centres and 3/8 inch (9.525mm) 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. The LFA-Q has a twin-boom system. Each section is 38.1mm square with 1.6mm wall thickness. The booms are joined each end to one another by a second piece of the same material used for the boom. A UV protected Boom Guy system is also provided with stainless steel turnbuckles for easy adjustment.
The LFA-Q is also provided with 2 boom to mast brackets, one on each boom and both brackets comprise of 4 U bolts (2 square for the boom, 2 round for the supporting mast) which have been formed from marine grade stainless steel.
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 foundhere
