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 or AGTC_lite by F5FOD/DG7YBN | |||||||||||||||
This combination of software provides excellent accuracy. Segment Density is | |||||||||||||||
25 segments per half wave. | |||||||||||||||
2. Temperatures initially used: Tsky=20 degrees;Tearth=350 degrees | |||||||||||||||
Temperatures now adjustable to Tsky=27 Kelvin. Tearth: Rural = 460K Kelvin, Residential = 1800K Kelvin, City = 7900 Kelvin | |||||||||||||||
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. 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 | |||||||||||||||
Temperature Calculations by Brian Cake, KF2YN for details. | |||||||||||||||
12. Manufacturer/Designer Legend: Single click on Sites in blue | |||||||||||||||
