| Only Antennas that have actually been built are posted in these Tables | ||||||||||||||||||||||
| Thanks to Vladimir, UR5EAZ for establishing the Interactive Mode in the 144 and 432 Tables | ||||||||||||||||||||||
| Thanks to Hartmut, DG7YBN for his ongoing support and many inputs to the Tables | ||||||||||||||||||||||
| Legend: | ||||||||||||||||||||||
| 1. L = Length in Wavelengths | ||||||||||||||||||||||
| 2. Gain = Gain in dBi of a single antenna | ||||||||||||||||||||||
| 3. E = E plane (Horizontal) stacking in Meters. | ||||||||||||||||||||||
| 4. H = H plane (Vertical) stacking in Meters. | ||||||||||||||||||||||
| 5. Ga = Gain in dBi of a 4 bay array | ||||||||||||||||||||||
| 6. Tlos = The internal resistance of the antenna in degrees Kelvin. | ||||||||||||||||||||||
| 7. Ta = The total temperature of the antenna or array in degrees Kelvin. This | ||||||||||||||||||||||
| includes all the side lobes, rear lobes and internal resistance of the | ||||||||||||||||||||||
| antenna or array. | ||||||||||||||||||||||
| 8. F/R = Front to Rear in dB over the rear 180 degrees of an antenna using either E or H plane. | ||||||||||||||||||||||
| 9. Z ohms = The natural impedence of a single antenna in free space. | ||||||||||||||||||||||
| 10. VSWR = VSWR Bandwidth is based a single antenna over 432.000 - 435.000 MHz with a | ||||||||||||||||||||||
| reference at 432.300 MHz. This parameter gives an indicator of the | ||||||||||||||||||||||
| antenna "Q" and what to expect with with stacking and wet weather. | ||||||||||||||||||||||
| 11. Ant G/T = Figure of merit used to determine the receive capability of the antenna | ||||||||||||||||||||||
| or array. Ant G/T (dB) = Ga - 10*log(Ta). The more positive figure the | ||||||||||||||||||||||
| better. Ant G/T is modelled in Tant.exe at 30 degrees elevation. | ||||||||||||||||||||||
| Notes: | ||||||||||||||||||||||
| 1. The programs used to calculate E/H Stacking,G,Ta,Tlos and G/T are | ||||||||||||||||||||||
| EZNEC 5+ by Roy Lewallen W7EL,4NEC2 by Arie Voors and Tant.exe by Sinisa, YT1NT/VE3EA. | ||||||||||||||||||||||
| This combination of software provides excellent accuracy. Segment Density is | ||||||||||||||||||||||
| 25 segments per half wave. | ||||||||||||||||||||||
| 2. Temperatures used: Tsky=20 degrees;Tearth=350 degrees | ||||||||||||||||||||||
| 3. Dipole Z is measured at 432.1 MHz | ||||||||||||||||||||||
| 4. F/R, 1st and 2nd Side Lobes (SL) have been calculated on a single antenna | ||||||||||||||||||||||
| 5. No stacking harness losses or H frame effects are included in the 4 bay gain figures. | ||||||||||||||||||||||
| 6. All stacking dimensions EXCEPT those marked with a "*" and "#" are | ||||||||||||||||||||||
| calculated from the DL6WU stacking formula: | ||||||||||||||||||||||
| D = W/(2* sin(B/2)) | ||||||||||||||||||||||
| Where: | ||||||||||||||||||||||
| D = stacking distance,vertical or horizontal | ||||||||||||||||||||||
| W = wavelength, in the same units as D | ||||||||||||||||||||||
| B - beamwidth between -3dB points. | ||||||||||||||||||||||
| Use vertical beamwidth for vertical stacking (as above), | ||||||||||||||||||||||
| Use horizontal beamwidth for horizontal stacking. | ||||||||||||||||||||||
| 7. Antennas marked with a "*" have stacking dimensions recommended by | ||||||||||||||||||||||
| the manufacturer or designer. | ||||||||||||||||||||||
| 8. Antennas marked with a "#" have stacking dimensions for XPOL | ||||||||||||||||||||||
| antennas by VE7BQH. | ||||||||||||||||||||||
| 9. Antennas marked with a "+" have some or all elements over 6mm. All others | ||||||||||||||||||||||
| are 4MM to 6MM. | ||||||||||||||||||||||
| 10. FD = Folded Dipole | ||||||||||||||||||||||
| 11. Manufacturer/Designer Legend: | Single Click on the Sites with Links | |||||||||||||||||||||
| 12. Convergence Correction: NEC2 and NEC 4 are incapable of handling complex | ||||||||||||||||||||||
| feed systems accurately like Folded Dipoles, T Matches, LFAs etc. | ||||||||||||||||||||||
| Convergence Correction using the KF2YN Excel program is required. | ||||||||||||||||||||||
| See DUBUS 4/2010 "The Correction of Convergence Errors in Antenna | ||||||||||||||||||||||

| Using this Chart: | ||||||||||||||||||||||
| While Gain is important, 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. Low sidelobe and F/R antennas with good (G/T) may | ||||||||||||||||||||||
| provide further signifcant benefit if you have local man made noise that is in directions where these | ||||||||||||||||||||||
| kinds of antennas provide additional suppression. | ||||||||||||||||||||||
