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
      Temperature Calculations by Brian Cake, KF2YN for details.
13. Manufacturer/Designer Legend:
   AF9Y = AF9Y K1FO = K1FO
   BVO = Eagle/DJ9BV K2GAL = K2GAL
  BQH = VE7BQH K5GW = Texas Towers/K5GW
   CC = Cushcraft KF2YN = KF2YN
   CC MOD = VE7BQH M2 = M²
   CD = CUE DEE  MBI = F/G8MBI/F5VHX
   CD MOD = VE7BQH OZ5HF = Vargarda
   CT1FFU = CT1FFU RA3AQ = RA3AQ
   DD0VF = DD0VF RU1AA = RU1AA
   DJ9BV = DJ9BV SHARK = SHARK (Italian)
   DJ9BV OPT = DJ9BV SM2CEW = SM2CEW/VE7BQH
   DK7ZB = DK7ZB SV = Svenska Antennspecialisten AB 
   EKM MOD = SM2EKM W1JR = VE7BQH (Mininec error)
   F9FT = F9FT WB9UWA = WB9UWA
   Flexa = FlexaYagi YU7EF = YU7EF
   G0KSC LFA = G0KSC UR5CSZ = UR5CSZ
   G4CQM = G4CQM UA9TC = UA9TC
   HG = HYGAIN Vine = G0KSC Design
   I0JXX = I0JXX YU7XL = YU7XL
   IK0BZY = IK0BZY InnoVAntennas = G0KSC
  WiMo = WiMo Tonna = F9FT
  DG7YBN = DG7YBN
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.
