Below is the VE7BQH 6M Antenna comparison list. Take special notice of the antenna SWR bandwidth and the new F/R (Front to Rear) section. This addtional field helps to indicate how well an antenna has been designed. The higher the F/R number, the better. The SWR figure is highest SWR between 5.0 and 50.500MHz

| Notes: | |||||||||||||||
| 1. All antennas are now calculated in Eznec5+ by by W7EL, Roy Lewallen. | |||||||||||||||
| 2. All antennas are in free space and horizontally polarized. | |||||||||||||||
| 3. One wavelength at 50.150 MHz is 5.98M or 19.62' | |||||||||||||||
| 4. "E" represents the horizontal plane; "H" represents the vertical plane. | |||||||||||||||
| 5. F/R is Front to Rear in dB over the rear 180 degrees of an antenna using either E or H plane. | |||||||||||||||
| 6. Z ohms is the natural impedence of a single antenna in free space. | |||||||||||||||
| 7. VSWR Bandwidth is based a single antenna over 50.00 - 50.300 MHz with a reference of 1.00:1 at 50.150 MHz | |||||||||||||||
| 8. G/T is not included in this table as the ratio between cold sky and ground noise is small. ie 2400K cold sky | |||||||||||||||
| versus 3000 - 4000K ground noise. Therefore, G/T does not produce useful results on this band. Very Low side lobes | |||||||||||||||
| and F/R on this band produce no specific improvement in G/T based on pure sky noise and ground noise. Assuming | |||||||||||||||
| reasonable side lobes, F/R and good VSWR bandwidth, Gain is the most critical parameter on 6M. | |||||||||||||||
| 9. Antennas marked with a "*" have stacking dimensions recommended by | |||||||||||||||
| the manufacturer or designer. | |||||||||||||||
| 10. Force 12 or Create antennas are not included as no data is available from the manufacturers. | |||||||||||||||
| Using this Chart: | |||||||||||||||
| While Gain is very important on on this band, other factors like ease of matching and wet weather performance should be | |||||||||||||||
| considered in the your decision making. Antennas with 50 ohm feed systems and good VSWR bandwidth (Q) may be the best | |||||||||||||||
| choice depending on your location. Although there is no advantage to low sidelobe and F/R antennas based on sky noise | |||||||||||||||
| and ground noise (G/T) these antennas may provide signifcant benefit if you have local man made noise that is in | |||||||||||||||
| directions where low side lobe antennas provide additional suppression. | |||||||||||||||
| Stacking is an issue on this band due to the large optimum spacings. While the longer antennas are very attractive | |||||||||||||||
| because of there superior gain, if severly understacked, the gain advantage may be quickly lost. | |||||||||||||||
