2m 14elements CROSS Antenna 2mCROSS14WA Wideband

Full frequency range 144 – 146 MHz 2m 14elements CROSS Antenna 2mCROSS14WA Wideband with 7+7 elements devoted for EME and LEO Satellites. Used as part of “Big Leo Pack” with added RHCP Kit

2m CROSS Antenna 2mCROSS14WA is designed to cover the complete 2m band 144 – 146 MHz and any radio modes like CW, SSB, FM, Q65, FT8, and all kinds of communications like DX-ing, Contesting, FM work, and LEO satellites

 

LEO satellites – Low Earth orbit satellites in Ham Radio.

LEO satellites have a circular (or elliptical) orbit at the height of 250–2000 km from the Earth’s surface. The maximum time during which a satellite is above the local horizon for an observer on the Earth is up to 20 min. This time is used to transfer data, images, and photographs to selected ground stations positioned in strategic locations.

Several Low Earth Orbit (LEO) OSCAR satellites use frequency modulation (FM). These are also commonly referred to as “FM LEOs” or the “FM Birds”. Such satellites act as FM amateur radio repeaters that can be communicated by using commonly available amateur radio equipment.

Wide-band operation with low SWR. The antenna could be used for any radio modes like CW, SSB, FM, Q65, and all kinds of communications like EME, DX-ing, Contesting, Repeater work, and LEO satellite…

What about Orthogonality and related to that isolation between antennas (coupling) say SM5BSZ

“The NEC simulations above show that an isolation of 20 dB is sufficient. This means that the obvious way of checking a cross Yagi is to connect one of the feed lines to a transmitter with known output, and a power meter and a dummy load to the other. The attenuation is then measured directly through the power arriving at the dummy load. If it is below -20 dB compared to the transmitted power everything is fine. ”

Excellent results of isolation achieved -30 dB. Much better than SM5BSZ suggested:

What others say:

2m 14elements CROSS Antenna 2mCROSS14WA at SM0TGU

2m CROSS Antenna PA144-CROSS-14-3.5A at SM0TGU On-Air

 

This is the best antenna I have mounted so far when looking at the material quality!
The initial test via RS-44 satellite was perfect, with more gain compared with my old 6 el Yagis. I also think the antenna has less noise.

Antennas-Amplifiers Product Benefits. A Major advance in antenna design.

  • F/B and G/T superiority. All antennas have been calculated using state-of-the-art full 3D EM modeling software including the influence of the boom, bracket, baluns, and connectors. The performance of antennas designed using these techniques is exceptional, far better than antennas designed using the EZNEC program.
  • No tuning antennas. Before dispatch, we assemble and test each antenna’s characteristics. No need to tune any element to get perfect SWR on the intended frequency range. Everything is pre-tuned.
  • Easy to set up. Everything is labeled, just put number to number. Everything is included in the box: Antenna, balun, bracket, and guy rope support if needed. Yours is to assemble and have fun!
  • Mechanical properties. We believe that our antennas are the world’s strongest antennas and are mechanically constructed much better than any antennas from other manufacturers.

The old name of the antenna was PA144-CROSS-14-3.5AP

If this 14 elements 2m CROSS Antenna 2mCROSS14WA is too big:

Look at the smaller 8 elements rear mount Yagi 2m LEO Pack Antenna 2m8CROSS

Or if it is too small look at the ultimate 20 elements 2m CROSS Wideband Antenna 2m20CROSSWB
