The DXSR (DX SYSTEM RADIO) antenna, model DXSR VB 800 is a multi-band vertical antenna.
Frequency : 1.8 Mhz to 52 Mhz
Length : 7m
Type : Fibre-glass
Length : 5.25m
Max. power rating : 800W
VSWR : 1.8:1 from 3.5 Mhz to 30 Mhz without antenna tuner
Radial length : no radials or no ground are necessary
Weight : 5 kg
Rated Wind velocity : 50 m/s
NOTA : This antenna was used for HF operation from February 2002 to April 2005 at the top of the tower (15m) but in front of such results so catastrophic
I decided to stop using it any more. This antenna works like a dummy load from top band (160m) to 40m. On the shorter bands it is quite ok.
This antenna dissipates power in the matching circuit, it cannot be used at rated power (800W) as indicated on the instruction manual.
100W key down should be a maximum. If you set higher power, the SWR goes up and never ending. But some minutes standby and the SWR is back ok, this is a bit amazing.
If you need a good dummy load, try it !!!
VB-800 or dummy load, this antenna has the same performances !!!
