DISCONTINUED INNOV 5 Element 50MHz LFA-Q Yagi Wide Spaced (7.5m)

5 element Low Noise, Heavy Duty QUAD

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 the LFA-Q could be the one for you!

Improved Performance

The LFA-Q. Direct 50 Ohm impedance (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, the LFA-Q stands out for two more major benefits. High levels of forward gain and its' extremely rugged design which make it ideal for installation where harsh weather conditions are commonplace.

Multiband, Performance-Busting Design

The antenna is made with tapered elements 16mm centres and 13mm outer sections with 2mm wall thickness. The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with the antennas which will support 2 inch (50mm) masts. The LFA-Q has a twin-boom system. Each section is 45mm square with 2mm wall thickness tapering to 40mm with 2mm wall at the ends. 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.

The antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, 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.
