| qrv I am on 2 m and 70 cm with a Icom IC-821H Transceiver and on SW
6m-160m with a the Yaesu FT-450, for Digital Voive (DV) and FM Mode
with the 2011 new D-Star Icom ID-31E for 70 cm

Antennas for 2m and 70 cm
 ...
70cm vertical for D-Star |
| My 2 m 17 el. Yagi after F9FT, boom length 6.5 m technical data 15m above ground and 11 el. Vormast Yagi for 70cm, 365m asl |
To the VHF/UHF antennas a simple rotor belong.
For the current supply of the Transceiver and a Transitor Pa for 2m two
power supply units serve 300 Watts.
A constant voltage switch power pack SEC1223 with 13,2V and 21A becomes
by a Zetagi 1250S with 40A
and adjustable output voltage supplements.

| TNC, Pa 2m, match box 10m, SWR meter of Zetagi, Sec1223 |
For package I use the TNC2H-DK9SJ von Symek, paxon software and a 2m/70cm
vertical.
2 antennas for the short waves
QRV to 40 to 160 m
For the high-frequency bands 40 and 80m I use a 40,8m long Windom self-'s building wire antenna with 1:6 Balun.
ON4AA-website for a koax-drive Windomantenna here.
The middle point of suspension is in 9m height at my UKW mast over the
house.
The diagonal thighs end in 5-6m height at a tree
and at a cross-beam branch in the garden. By the diagonal arrangement
otherwise the vertical becomes radiation due to
the small height above ground reduces.
The antenna has thereby similarity with the following arrangement:
The illustration originates from the electronic yearbook
1977 p.171 also of DL7KM tested dimensions.
QRV to 10 to 20m
In November 2006 I have a Rotary dipole for 10/15/20 m von ECO/Italy
also
Rotor installs. Since my VHF mast is in the way, I reach only one angle
of rotation of 160 degrees.
Yagi- and Wire-Antennas in Winter
With the Tuner MFJ-986 are better on 10, 12, 15, 17 and 20m a SWR than
1,5
adjustable.
