This is a 6 meter full wave loop or can be mounted as a delta loop, transmitting antenna. Covers the full 6m band or it can also be tuned out of band if you need.

It’s getting to be more challenging to receive the JT65B transmissions from the recently launched 4M (Manfred Memorial Moon Mission) lunar payload. The 13-character onboard messages posted from around the world prior to launch were expected to be transmitted this week and will be repeated. On October 25 Ghislain Ruy, LX2RG, of LUXspace said signals from the 4M payload were quite weak.

You can see on this video my new created device after four years work in designing several remote control systems to tune the variable capacitor of a Small Magnetic Loop Antenna. The antenna can be carried on my back, with a light and simple Back Support described on my web page, or I can temporarily fix the antenna on a balcony or window adjusting the antenna”s resonating frequency from a distant place.
This is both part 1 & 2 of explaining how I constructed my Ham Radio “To Go” box en ligne casino france so KEEP WATCHING AFTER it says THE END. For Portable use both in house and if needed emergency, field day, etc. I plan to use the anderson strip to power my Elecraft KX3 when it arrives to! Will attached KX3 with a bit of velcro or once I get KX3 will see if another way. I have room over my 857 or will change 2 meter mobile to a smaller one(I have a FT-1500 which is smaller)

Testing a lightweight HF magnetic loop antenna made from 7 metres of RG58 coaxial cable. Contacts were made on 40 and 20 metres during the Lighthouse Weekend. It uses just three main parts: the coax itself, an air-spaced variable capacitor (approx 50 – 100pF max) and a T50-43 ferrite toroid. The toroid is threaded over the coaxial cable. RF from the transceiver is fed via a 2 or 3 turn winding over the toroid (experiment with this for lowest SWR). The coax inner is left unconnected; only the braid is used here. The loop is for low power use only – it will take 10 – 20 watts before the variable capacitor arcs over. Performance is, as expected, somewhere between a smaller pedestrian mobile magnetic loop and a full sized wire antenna. It would be improved if the variable capacitor was a low loss type and the coaxial cable was soldered straight to it. While there’s enough information above to make your own, it’s worth checking out G4FON’s website ( www.g4fon.net ) for similar loops. My loop is closest to his Version 2.

this is my 14mhz delta loop home made out of a 30ft fibreglass pole vertical section and 18f horizontal section,i have worked usa,brazil,argentina,africa,china,europe with this antenna with a yaesu ft847 and 50watts. The loop is fed in the centre for horizontal polarization and as you can see i have had good contacts all over the world.
Hey guys the edition sucks I know but Is just a sample to get some input about if is working or not! I will be updating this video later on. On this video I test in this order a Rubber ducky/Cloverleaf/SPW and last the helical. Thanks for watching and stay tuned for more info. Note that my helical antenna doesn´t have any type of impedance matcher.
First test with Arduino tuner. The Lock button on FT817 is used to tune the capacitor. On 20 and 40 meters (actually) there is a fast tuning function. On different frequencies all the capacitors course are analyzed to find better SWR. Arduino is used to drive the servo,read frequency,swr and lock command from FT817 and set FM mode for tuning.At the end of tuning procedure Arduino set again LSB or USB depending the frequency. Based on Alain De Carolis project (alain.it)
This is a new Palstar AT2K tuner that I purchased, and I hope for it to be the last antenna tuner I ever buy. So far it’s living up to that reputation flawlessly. The construction is top notch, the level of attention to detail that Palstar has put into this tuner is stellar, and I wouldn’t hesitate to recommend this tuner to anybody, even with the most demanding antenna tuner needs.
