DG7YBN / 50 MHz VE7BQH Antenna Table

  Issue 36, Mar. 2019




                             

     
Note the change in this table:

The 50 MHz Antenna Table is a compilation of simulations of 2 and 4-Yagi-Bays at 50.1 MHz. The main purpose of this table is to enable you to select a Yagi design by its performance level for non-terrestrial weak signal work such as EME. Levels of man-made noise have risen and its levels are documentated by the ITU and others. Thus at higher Tearth the Y-factor for 50 MHz is at a reasonable number to move from judging antennas for this band by gain to "Antenna performance is best determined by the G/T of the antenna". See End of table.

Thanks to Hartmut, DG7YBN for his ongoing support and many inputs to the Tables
Legend:
1. L = Length in Wavelengths
2. Gain = Gain in dBd of a single antenna
3. E = E plane (Horizontal) stacking in Meters.
4. H = H plane (Vertical) stacking in Meters.
5. Ga = Gain in dBd of a 4 bay array
6. Tlos = The internal resistance of the antenna in Kelvin.
7. Ta = The total temperature of the antenna or array in 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 50.0 - 50.3 MHz with a
reference at 50.150 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 Ant 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.
2. Temperatures initially used for producing Antenna Temperature: Tsky=4225 Kelvin;Tearth=6000 Kelvin
Temperatures now adjustable to Tsky=5640 Kelvin. Tearth: Rural = 29640 Kelvin, Residential = 100600 Kelvin, City=271000 Kelvin
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 50.000 - 50.300 MHz with a reference of 1.00:1 at 50.150 MHz
8. 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 or AGTC_2lite at 30 degrees elevation.
9. Antennas marked with a "*" have stacking dimensions recommended by
the manufacturer or designer.
10. Force 12 antennas are not included as no data is available from the manufacturer.
11. FD = Folded Dipole
12. Convergence Correction: NEC2 and NEC 4 are incapable of handling complex
feed systems 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.

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. Tearth noise has now risen to the point on this band where low sidelobe and low F/R antennas
can provide signifcant performance benefit. Antenna performance is best determined by the G/T of the antenna.
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.
