The newest VE7BQH-List includes 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 program used up to now to calculate E/H
Stacking,G,Ta,Tlos and G/T
is YAGI
ANALYSIS 3.54 by Goran Stenberg,SM2IEV. There are errors in this program.
The stacking
gain in the E Plane is fixed at 3 dB regardless of the stacking distance.
The error
for a 4 bay gain is about 0.1 dB as is the G/T. Use of non DL6WU stacking such
as for XPOL
creates even more error. The error for XPol stacking is about 0.2 dB or
more
for a 4 bay
gain and G/T. To make this table more accurate,effective Aug 1, 2009. I will
be using
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 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 10MM elements. 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.
