One for the antenna aficionados…
Years ago when I first showed an interest in radio, a very senior radio ham said to me “son, there’s more garbage talked about antennas than any other subject in the ham radio world” (actually, he didn’t use the word garbage.)
One thing that has always puzzled me since being licensed, is how a vertical on the HF bands even using low power, will absolutely beat a beam hands down.
Today was a classic example, as if by some type of sorcery, my vertical CB antenna just punched straight through almost every pile-up on both 10 and 15 Metres.
Low angle of attack is one of the common reasons I’ve heard.
I did a little Googling and came across and I quote…
"As a general rule of thumb The lower the angle of radiation, The further DX you will work.
And the Higher the angle of radiation, the closer dx you will work.
This also becomes null when considering what frequency you are referencing. The higher the frequency the less effect the atmosphere will have."
Now this doesn’t exactly explain, why a cheap CB antenna should beat very expensive beams using big power. …Ok certainly by no means every day, but just occasionally there are days when my vertical works more like a magic wand than an antenna and today seemed to be one of those days!
I’d be grateful for any thoughts?
