Hello,
Right to the point. At HD2A we installed an Inverted L with the following
dimensions:
vertical portion 16m
horizontal portion 26m.
The horizontal wire goes with slightly upward with with its end at 19m above
the gound.
The ground system - 4 x 6ft ground rods at the base
- 34 x 42odd m radials on the ground
No matching device is used. Fed directly with RG8 coax.
The SWR was at 1.5 to 1.8 on 1.832 now it is 3:1 at the same frequency with no
visible alterations to the antenna except the rain season.
The question: what could cause the SWR increment? any suggestions to bring it
down and keep it relatively stable.
Thanks in advance,
Alberto, Alex
HD2A Team
