This was "measured" with a 10 dollar AliExpress EMF meter on a roof. Over 1900V/m.
The real measured value with a calibrated Narda was less than 2V/m.

Je refais le réflecteur de ma Moxon 868MHz (Constantine) : 1mm d'erreur, c'est trop pour la symétrie du lobe. Fil 1,7mm ajusté au boîtier PETG.
Bientôt le NanoVNA avant de sortir la colle T-9000.

If you already own and operate GMRS radios as a part of your emergency preparedness kit, have you upgraded the antenna, or do you stick w factory? Factory antennas are, well, a compromise. Consider upgrading. #gmrs #emergency #prep #antenna #radio SignalGuides.com
I set up this Chameleon CHA BV vertical antenna for the 20 meters to see how it react in the wind. I had to make some modification to the original project to make the whip more rigid and not bend in the wind.

Okay, this is neat: anybody want some late 1940s-early 1960s RADAR TOWER MOUNTS? This guy bought a house and it has them installed in the front yard. A previous occupant had used them to make a swingset, but he just wants them gone […]

The middle piece from the previous filter unit kind of coil now with just straight through connectivity and extended cable shielding before going to the connector screw.
a plastic radio base cone with the extracted contents which includes a _massive_ coil joining the shield and centre wires, clearly some kind of CB-related filter
On site to make some modifications on the #mediumwave TX #antenna at 747 kHz
Also #hamnet at #FM repeaters on 2m 70cm and 23cm.

Checking on my GAP Titan DX. Still ok thanks to the guy lines. Winds supposed to be worse tonight. I hope it stands, this has been an excellent antenna. I’ll be very sad if it doesn’t.

My "Works on all bands 40 to 6m" antenna doesn't... At least not well.
This is my solution. I fabricated a copper bracket to mount a 40m and 20m hamsticks and a Wilson 5000 (tuned for 10m) so I don't have to […]
