Materials in hand. Now...
What to build?
I have plenty of raw materials at hand. Even have everything required to build an "Arrow-style" duplexer. Now I have to decide what antenna to build for the sats. An Arrow-copy? An IOio? Or... something else?
Thoughts? Opinions on those antennas mentioned? Something completely different?
Come on! Help me make up my mind!
Grid Square: EM50vo
Icom 751; 40M Loop Skywire & 17M Vertical
- George U. Potter Lodge, #912, F. & A. M. of Alabama, Historian
- Valley of Mobile, Orient of Alabama, A. A. Scottish Rite, S.J.
- Dave Langham Chapter, #536, Order of the Eastern Star, Sentinel
- Order of DeMolay, Mobile Chapter, Chapter Dad
I've built several styles over the past year.
Do you intend to use this from a car?
From the field?
At home with a TV rotor?
I can make you a recommendation based on those answers. I would not waste my time with a tape measure beam.
The smaller 3 element designs such as iOiO, CJU, and K5OE Handitenna are all adequate for reception of any of the current mode J birds' down links.

If you have a 2m mobile with antenna, I'd start with a CJU for 70cm receive with an HT, and use the car for the uplink. Full duplex, and you can operate in the AC with the CJU out the window!
Another thing I would like to eventually build are side-by-side quad or cubic antennas 2M/70cm.

The link I posted is to an article with basic instructions on how to build it. Unfortunately, I believe you have to subscribe to see the complete article.
