10M Antenna and operation time
« on: July 21, 2015, 1430 UTC »
Hi everyone. This questions regards a possible Antenna for this project.

I need a compact Antenna for the 10M Band. It can't be too complex nor large beacause it's going to be installed on a (pretty) high tower with strong, storm like winds every now and then. I can't, under no circumstance, run experiments up there. Two ideas have formed in my mind and I would love to get your opinions.

Either way, I'm going to install a wooden 3mtr. pole up there. Thick enough to withstand the heavy wind. That pole allows me two possible Antenna configurations:
  • A loaded (in the middle) 1/4λ vertical Beam. I'm could to staple the wire to the wooden pole and insert the load coil in the middle in a weather proof box. Question  II want to use the metal platform as the electrical counter part itself. I wonder about... can an electrcal counterpart (Ground) be too big/large/long? Okay, I guess I can test this Antenna on the ground. We have a closes bridge around here. Full metal construction.
  • 2) An Inverted-V. I have a lot of good experiences with this type. The platform is also wide enough for this kind of Antenna. Also, I could shorten it with inductors, too.

And there's a completely different question: from what I read in all the propagation charts lately, it seems that the best time for operation on the 10M Band is during daytime. Is there any use in having a Beacon operationg during night time?

Kind regards,

Bump. :)

Basically, I curious about what kind of Antenna you'd use for the  project in context. :)

I've used a 102" stainless whip on a standoff arm back in the day.
@ 140' it performed very well.

stay safe, good luck
