The Predator series antennas are designed under extreme demand levels. Getting several bands in one system, without any of the bands are affected. Several monobanders in a same antenna.
This performance is characterized in that:
The optimization of these antennas makes the radiation lobes are clean and you can listen to all stations that reach your S-meter without QRM and QRN alter the audio clarity.
Direct feeding is 50 ohms, using supplied Balun.
The bandwidth is similar to OWA, with the best technology development for the entire width of the band, and have low SWR.
Its ratio of F / B is medium to high, offsetting the high gain front.
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, 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 EAntenna antennas are insulated from the boom, with German clamps PP (Polypropylene, -30 ° C / +60 ° C).
The EAntenna 40MDY3 is a 3 element yagi for 40 meter band (7.0 ~ 7.3 MHz) designed for stations that need a short antenna for this band. With elements of only 12.7 meters long and 10, 05m. boom, you can achieve incredible results in this band in both the DX and in contests. With the machines used in this antenna has been achieved without losing lightweight durability and resistance to the wind.
The coils are HI-Q design, which optimizes the frequency which is designed and minimal loss over any other physical system acortamiendo an antenna by winding.
The profit after so many hours in design, is of 7,5 dBi (in space) and 7,5 dBi to 18 meters.
Characteristics of the 40MDY3
The Feed in the EAntenna 40MDY3 go directly to a 1:1 balun to 3 kW (included in price) and directly through a single coaxial cable drop 50 ohms.
Simple and quick, because the elements are attached by screws DIN 912 being inserted into aluminum for a lifetime installation, high pressure clamps on the ends to fit.
The fastening the boom on each element consists of an aluminum U 100 x 40 x 500mm with 4mm. thickness. and a tensioning system for both elements to the boom to get resistance up to 160 km/h. no doubt. The plate to the mast is 10mm. thick and 4 U-bolts of M8 both the mast and the boom, and like all antenna hardware, stainless steel.
Antenna very solid construction, and with an acceptable weight.
