Re: EFHW/RW - Attaching wire to balun

How does this look? The scale is 1cm for major lines.

Re: Bring lots of different types of antennas, just in case

That's it! It's well designed and comes in a great case. As far as size and weight it's about the same as a large folding camping chair when packed up.
try it at the seaside
That's a great idea!

Re: EFHW/RW - Attaching wire to balun

I'm working on that exact idea - a housing with a 9:1 unun and a choke, and those brass connectors that are used for linked dipoles glued to the outside to connect the wires. I have a 35.5/17 foot EFRW as my primary home antenna, but I can have both 35.5 and a 29 foot wires for portable operations. ...

Re: Bring lots of different types of antennas, just in case

I like the idea. I think I forgot about it because it's too big for me to take on an airplane, but for a local activation it would be perfect! However, I'm glad I broke the base of the magloop close to home - I was able to modify the design with a thicker base and reprint it that evening. 73, Mike, ...

Re: Bring lots of different types of antennas, just in case

Ok, now I feel like a dummy. I have a TransWorld TW2010 (pretty much a commercial version of your double T bar) but I was concerned about taking up too much space in the car. Next time...

Re: Bring lots of different types of antennas, just in case

Bringing the "toy" vertical was a mistake, but I think it's good to have a wire antenna as primary, and the magloop (or other non-wire antenna) as a backup. I was in Arizona last year, and while I was allowed to put an antenna in a tree, there weren't any good candidates so I ended up usin...

Bring lots of different types of antennas, just in case

I activated Greenbelt Park (US-0668) on Saturday. By half an hour of operating, I was on my third antenna. I started (or tried to start) with a magloop, but a gust of wind knocked it over and broke the base. I then tried using a very small loaded whip, but after 10 minutes of calling CQ POTA without...

Re: TR-35 group/forum

Thanks. I’m planning to set it relatively low. My trusdx rigs’ sidetone is tied to the overall volume, so when I turn up the volume to dig out a weak signal the Sidetone is painful!
