A Simple 7 Bands Small Space HF Antenna 

Yep some good points. However, the RT100 is typical of many auto tuners in that it’s impedance range stretches up to around 800 ohms. The MAT 40 is about double that. Now, taking my 9m wire into consideration, let’s look at 14 MHz, the wire is getting close to a 1/2 wave. Already the feedpoint impedance will be in 4 figures. I’m unsure that the RT100 would cope if asked to be a feedpoint tuner. Same on 10m as a near full wave. Thanks for the comments, great to see the interaction. 73

@@timg5tm941 thank you for your kind words. I did not really measure the the wire exactly, not even talking about considering the velocity factor, but I had absolutely no problems with the RT100. I think this setup is a prime example where the concept of a "random" wire length comes into play. As long as you hit no super high impedance you'll be fine. A 4:1 in front of the antenna port would also sort this out but that's not really in line with a more streamlined setup. I often use the chinese 5.6m whip antenna on a mag mount, fully extended and matched with the RT 100 as my go to POTA setup for 20 to 10m. I was really surprised that the RT 100 gives a perfect match everywhere on the 10m Band, since it's nearly a half wave length. It really works exceptionally well and got me from southern Germany to the US, South America, Korea Vietnam etc. But anyway, great work from your side as usual. I really dig this kind of practical, out in the field types of videos. By the way, I already told you once over the air, you're making me poor because you made me buy the 891 and the RT100, but I am absolutely grateful for it 😅

@@_0815_ I’m glad it worked for you. The RT100 and 891 are a great combination using the ATAS mode. Keep on rocking! 73

Thanks!

Absolutely!

Fingers crossed Steve

Thanks Dave!

Hi Ben , thank you. From memory around 16 x 2.5m radials in four bunches of four radials.

Last Friday around 2:30-4pm UK time
