Thanks, Tim. I always learn a lot from your videos and get plenty of ideas.

so a million dollar question: for mobile operation whip + antenna tuner or baseloaded screwdriver antenna????

Thanks for sharing Tim. Not sure why, but my 20m resonant vertical works really well on 17m hi. Weird eh. 73.

I suppose you could try it horizontal as well . I can get the Xeigu g90 to tune both 12 and 17m on the 40-10 m EFHW and had decent results despite it not being one of the harmonic bands .

Very interesting - new setup to try for my CHA LEFS 40-10. Suggestion: Do a video on a square vertical loop - say each side 5 meters. Hear of good gain on that Regards Mike

Regarding the impedance of the coil, the maximum is obviously where no extra bit of wire is needed - but what about the minimum, how much is the minimum you need to choke off the 12m part of the antenna? How does it cut off, is there a sharp cut off between the 12m bit being choked and not being choked or is there a gradual increase as the inductance increases?

👍😁 phil, Suffolk.

As a QRP operator, I love 17 meters ! Its one of my favourites for making telephony contacts on <10 Watts. I really like your design, I only wish I had more time for both radio and building antennas, it looks super simple and something that even I couldnt mess up :D Could you make a video of you operating with the antenna please tim, i'd be very interested to see how well it does.

Welcome back Tim I'm new to the hobby and I've learned a lot from your videos. So take care because I'm always waiting for another video 😉 Enjoy the G90 73 de CS7BDO

Thanks for the nice video Tim !

Thanks 👍

I often go to the dark side - 11m - lol because the force is often as strong as 12m with a much bigger scope for QSO's . Hopefully that does not make me bad ? 73 M7BLC / 26CT3775.

Isn't it more efficient to use the collapsable telescopic whip (5 meters long maximum) on 17 and 12 meters (collapsing it on 12 meters)? I use it with a mag-mount on the top of the car (where the car body serves as a counterpoise). This setup needs no transformer (i.e. it avoids losses in the transformer).

Another short and good one. Thank you Tim!

Tîm... Oh Tim!! .. Thank you so much for a wonderful distraction from the insane world we now live in!!! ❤❤

Nice Tim, very nice indeed.

Hi Tim keep up the good work 👍

As it happens i have an Am-pro 20m mobile whip antenna in my cupboard. Its the black fibreglass spiral wound one with the top metal adjustable whip section and 3/8th mount. Last time i was active i remember some very good results mobile from high ground. I also used it on a mag mount though im not sure if there was a fair bit of stray RF hanging around. I'm just wondering if it would benefit from putting it on a pole with a bracket and maybe a balun and a radial or two rather than a magmount??

Hi Tim, i just recently discovered your channel so have only viewed a few vids but i just have to say how brilliant they are and what a great presenter you are. An easy listen :) I'm a G0 but havent been active for years mostly due to life getting in the way and moving house years back. I just had my TS850S serviced and overhauled and im keen to get back on the air. A lot of people think you need big bucks and big money for HF antennas and of course size can be an issue if you are short of real estate like me. But as youve clearly demonstrated, all you need is a pole and some bits of wire . You have inspired me. Id really like you to show things like the types of poles you use, how they assemble and lock together, also power sources. Obvs my 850 isnt ideal for mobile but its what i have right now. Can you explore power sources, eg ideal batteries for powering 100w HF etc.. Thanks again for yyour great contact TIM. Your enthusiasm shines through ...

is it possible to slope the ground as well...? my efhw follows a sloped ground almost in the same angle.

Well, excellent, a great look at exactly what I'm planning to do! So many thanks to you Tim G5TM, and thanks also to Ric DJ0IP for his very good article on a vertical doublet. I currently have a horizontal 20m doublet, fed with open wire constructed ladder line, which I have been very pleased with, though I must confess I haven't done much HF since getting licensed, having done much more on 2m. But I had put a lot of thought into my existing doublet, including modelling and careful choice of a 1:1 current balun. I've just got back into radio recently, including the HF side of things. But a failed attempt to join in with a local 80m net made me realise I was probably trying to receive a vertically polarised ground wave on a horizontal antenna. So rightly or wrongly I'm going to try transforming my 20m horizontal doublet into a 12m vertical doublet and see how it goes. I had already settled on a 12m Spiderbeam pole, and I'll be re-using my ATU, balun and ladder line etc. In the future I can always revert, or even have both, but the vertical may well be all I need. I'll probably be foregoing 80m, but 40m and up I think will be fine. We'll see... Thanks again for the video.

Nice to see you back Tim, hope you have more luck with the G90 than I had. Worked only for 5 weeks, Xiegu said NO guarantee because it was used outdoors !

I bet I could do this with my FT-710 too then too, right?

Welcome back Tim - good luck with the weight loss and fitness, I need to do the same! Nice boots those Scarpas ;-) 73 G0JLF

I hope things work out for you mate will be having a watch with your progress main thing is to look after yourself take care

Hi Tim Congratulations I managed to loose lots of weight by walking. I had always loved walking but am now fitter than I was in my 30's!! Great idea and note that walking and Ham radio does go together :) If you ever fancy a walk in Hertfordshire with two fellow Hams let me know 73 Tim G1HBC

Good to see you again

Morning Tim. Its excellent you are combining your love for amateur radio and the great outdoors. Please consider your diet, as I've found that even running 15km/week was not enough to drop off the weight, if you don't eat properly also. We need you around for many years to come 😁😁

Shwmae Tim. Very enjoyable Video. Loved the Music. 🎶

Hi Tim, nice to see you back after great time in ZL with family! To chose ham radio & hiking as the way of life is never too late! 😉👍 73, S51X

Welcome back. N1XXU

Great to see you back Tim! Hope you have fun with the G90 and your hiking!

Good to hear from you again. I am looking forward to your future videos, and good luck with the weight loss. 73 M0FRH

The south face of Kingley Vale isn't much easier coming down than it is going up. There'a a good slighlty longer route up on the path that leads directly towards the trig where there are a couple of quiet clearings. Good luck!

Nice presentation Tim. Can the choke be used for 11meters or need to be changed. 73s Rob

I got into SOTA to get fit. I started with a G90 and it was great. But when I started doing activations with more than 3000 ft of elevation gain, I found that the radio was too heavy. I switched to a FX-4C. I turn 57 in November and have moved from Utah to Belgium. I plan on driving to France, Switzerland and Germany to do activations. Maybe I'll get a KX-2.

All the best, Tim. I'm looking forward to what's to come with that radio and your antenna ideas.

Good to see you back Tim

Hi Tim, I think I’m about the same age as you and have a number of radios to get out and about with so you’ve inspired me to do the same. I shall watch your journey with interest!

Really looking forward to the G90 videos. Have a look for your local parkrun. Literally changed my health ten years ago.

Hi Tim welcome back and welcom to the G90 club

Look forward to seeing you in Kingley Vale a lovely place to explore.

I’m sure you will love the G90 Tim!

Exciting stuff, Tim. Welcome to the G90 camp. Not the lightest of radios for hiking but VERY capable. A 6Ah LiFePo4 battery pack is a perfect match. In fact, even a 3Ah LiPo works well. Make sure you turn on the speech processor and you're good to go.

Great to see you back here Tim. Good luck on your new adventures.

Can the wire on a G5rv jr go forward in an inverted v rather than downward

Tim, I’m a new general and I love that G90! Tons of info out there check out Walt on from Costal Waves and Wires. Very experienced with the G90. Luck and Godspeed with the health I’m on that journey myself! Love your videos!

great radio, my go to for POTA
