Let's hope for a little more 10 meter activity!
La banda de 10 metros está mejorando en las últimas semanas. Ojalá tengamos más participación.
The 10-meter band is improving in recent weeks. Hopefully we have more participation.
I'm going to operate the arrl 10 meter contest. 1st time. Im wondering what antenna most people use. Vertical or horizontal? Im asking because I have a 80/10 efhw that works pretty good. But I just adjusted the swr and erected a 5/8 vertical ground plane antenna for 10 meter. Which is better on 10 meter? Vertical or horizontal?
My guess is most people on 10 meter are using a vertical. Unless they are using yagis. I'm just guessing. My concern is the difference in polarity and signal loss. My yaesu rig has two antenna inputs so it won't be a chore to switch between the two. Im just trying to get a grip on the vertical/ horizontal question.
I plan to play around some too. I normally use my ZS6BKW for HF use - it will load up on 10. I also have an old A99 laying in the shed from my CB days. Might drag that out and prop it up in a tree for a quick and dirty vertical.
I put up a hy-gain spt 500 penetrator. Its 41 ft to the radials. I was working a qso with my brother in law on 10 meters. He has the same 80/10 efhw I have. I had a better signal,, tx and rx using ef to ef. The signal from my vertical to his efhw was maybe 20% lower. I just gave him an old antron 99. Interested in how that will work out. By the way, he is around 30 miles as the crow flys.
Antenna polarization on 10 meters is mostly important if you are working ground wave. That is, you are not working skip, via the ionosphere. If working ground wave vertical is usually preferred.
But for the contest you will hopefully be working via ionospheric skip. What every your polarization is will shift and could be horizontal, vertical or anything between on the receiving end.
So use whatever you have and hope for some good skip conditions. Vertical, horizontal, EFHW, dipoles, inverted vee are all good on 10 with the help of some sunspots.
Unless that recent CME has some effect, it's going to be a slow contest. Been playing with FT8 all week, and it seems to pick up a bit early afternoon, but otherwise 10m is pretty much dead.
