The set-up was this:
- MFJ-1979 telescoping mast (17ft tall, extended)
- Vise-grip antenna mount
- 2 (and then 4) 1/4-wave radials
With two radials laid out on the ground, I attached the mcHF to the antenna and heard a good number of strong stations. So far, so good.
Upon answering a CQ'er the mcHF's SWR meter showed 3:1 so I immediately stopped to confirm what I was seeing with the antenna analyzer, thinking I might need to decrease the length of the mast just a bit.
|Resonant but high SWR|
Two more radials were then added with very little effect. A 2 MHz sweep centered on 14.060 MHz showed that 2:1 was as good as I was going to get without some sort of Z-matching network.
Moral of the story: Even a resonant antenna can have an unacceptably high SWR.
An antenna tuner would have easily taken care of this problem and one is on the way for the mcHF,
|As good as it gets & not good enough|
My next bike trip with radio will include a PAR end-fed, nylon cord and a weight - hopefully this Saturday.
