EAntenna LFA antennas for 70 MHz represent the largest development in
antennas with moderate boom length for a single performance.
This performance is characterized in that:
You can listen to very low signals without noise QRM and QRN alter audio clarity.
Direct feeding is 50 ohms, so there is no loss whatsoever regarding adaptation lines.
The bandwidth covers the entire band with low SWR / SWR.
The radiation pattern is wide, so that the signal is not as selective as you rotate the antenna a minimum.
Its ratio of F / B is high, since only antenna boom lengths can get exaggerated.
The gain is comparable with other models of antennas always larger in dimensions.
All this is explained because in EAntenna:
Millimeter by millimeter, manufacture and build CNC machines and / or prepared to hundredths of a millimeter measurements for an accurate measurement.
It takes care of every piece of aluminum, by filing them smooth exterior and interior. All this by hand, by skilled and prepared for a final product of extreme quality.
All hardware we use is in stainless steel AISI 304
The T5 aluminum used is 6061/6063 and 6082 T6, the best alloys for manufacturing antennas and resistant to the weather elements.
Always LFA EAntenna antennas are insulated from the boom, with German clamps PP (Polypropylene, -30 ° C / +60 ° C)
30x2mm square boom.
Elements complete, ready to mount 13mm diameter and is 10mm LOOP.
Mast plate of 150x100mm with 6mm thick with square U-bolts M6 boom to the plate and U-bolts of M8 to the plate to the mast.
Features of the 70LFA4
An extra wide lobe makes this antenna ideal IS in summer, daily Tropo as for other types of propagation in this band as PET, MS and F2, among others.
Simple and quick, because the boom joints are very easy to assemble. And the elements are attached by clamps Without End (Hose Clamp) for fast installation and durable fastening.
Antenna very solid construction, and a very acceptable weight.
Available for enfasar 2 or 4 units in a short (under table include phasing), and to make a profit no big antenna can get.
