And check out the new 6m antenna performance table by VE7BQH at the bottom of this page!
Here you will find information on how antennas behave when stacked. The antennas found in the table are the ones currenly used by people on EME. For an antenna to
qualify for a place in the table it must have been built by someone, antennas that only live as computer files are not accepted.
Please note the addition of Z and VSWR bandwidth to the table. This will give people a good indicator of the Q of the an antenna and what to expect
with stacking and wet weather. There are antennas with very good G/T but they have not performed well when stacked and in wet weather.These new
parameters should give good real world indicators.

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 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 144.000 - 145.000 MHz with a
reference of 1.00:1 at 144.100 MHz. This parameter gives an indicator of the
antenna "Q" and what to expect with with stacking and wet weather.
11. G/T = Figure of merit used to determine the receive capability of the antenna
or array = (Ga + 2.15) - (10*log Ta). The more positive figure the
better.
Notes:
1. The programs used to calculate E/H Stacking,G,Ta,Tlos and G/T are
EZNEC 5+ by Roy Lewallen, W7EL and Tant.exe by Sinisa, YT1NT/VE3EA.
This combination of software provides excellent accuracy. Segment Density is as
follows: Reflector and Directors = 25 segments. Split Dipole = 29.
G0KSC loop = 39,39,7,7.
2. Temperatures used: Tsky=200 degrees;Tearth=1000 degrees
3. Dipole Z is measured at 144.1 MHz
4. No stacking harness losses or H frame effects are included in the 4 bay gain figures.
5. All stacking dimensions EXCEPT those marked with a "*" and "#" are
calculated from the DL6WU stacking formula.
6. Antennas marked with a "*" have stacking dimensions recommended by
the manufacturer or designer.
7. Antennas marked with a "#" have stacking dimensions for XPOL
antennas by VE7BQH.
8. Antennas marked with a "+" have some or all elements over 6mm. All others
are 4MM to 6MM.

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.

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 antennas are not included as no data is available from the manufacturer.

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.
