The newer VE7BQH-Lists include an
information about the SWR at 145,00 MHz (VSWR Bandwidth).
The antennas are
simulated with an SWR of 1,0 at 144,1 MHz . The DK7ZB-Yagis are simulated with
6-mm-elements, in practise the bandwidth is better with the recommended element
diameter of 8 or 10 mm! Please remember that the DK7ZB-Yagis are designed for
144,3 MHz, there is the gain a little bit higher.

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.
Z ohms = The natural impedence of a single antenna in free space.
9.
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.
10.
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
starting at
the Reflector is 17,17,16,16,16,15,15,15 etc
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.
