Last week I posted:
I put up a 160m dipole but now need to tune it. SWR at low end of band is abt
3 and at top end abt 5. From what I have read this means I need to shorten it.
My question is how much should I take off? A foot off each end?? Any good links
to sites that may explain this in some detail so I can learn?
So in response to a number of questions I got, I remeasured the SWR to find the
minimum SWR
- SWR checked at base of vertical coax run to 1:1 Balun, using a MFJ
259 analyzer:
- Freq- mhzSWRImpedance (X)
- 1.776.2130
- 1.84.3106
- 1.8453.374
- 1.863.773
- 1.894.877
- 1.916.083
- 1.94 8.189
So minimum SWR at
- 1.845 3.374
The dipole antenna length - each leg was cut to 126' and it is 30 ft above
sandy ground
As I may have said previously, I am weak on antenna theory but anxious to
learn. Any advice or direction welcome.
