Nicely done Tim. Shows what can be achieved to get yourself on air. A friend has a 'washing line' in a lengthy garden as a long-wire with matcher, no more complaints from neighbours funnily enough. Keep up the good work!
Good to get a contact with you last night Tim you were sounding loud and strong here with me Just goes to show what we can get away with antenna wise when conditions are good like they were last night. Looking forward to seeing the new shack ! 73. Sid
Is there no end to the versatility of the EFHW?! Another cracking video Tim , nicely demonstrates that you don't need a 100ft tower to make lots of great contacts! 73, Tom.
Mine is just 8ft runs similar to yours wrapped around my garden through some bushes and hedge plants. Put it up only for 80m as my Windom can’t cope with it. Good results on 80m brings them in and tunes easily working about 250 miles from Leeds.
Great stuff Tony.. if I had more room I’d do the same here for 80 as I just want t o work really around G, EI and maybe into F, ON etc on 80. Glad it works for you too 73
Great video Tim, enjoy your channel,.The half wave end does work well, I have built a couple based on Steve Ellington's videos. I am fan of dipole but very impressed with efhw. More to the point of low height, I was out with a good friend kite/ p with 10w chatting to DL on 40M, turned to look at the kite and it was on the ground :-)
Nice, what sort of power were you running and did it need matching at all? I need to sort some NVIS as my G7FEK only seems good for longer range, good in many ways but makes it hard to talk to UK :)
Hi Dave.. 100 watts and the swr was 1.7-1.9:1 from 7100-7200. Therefore I didn’t need to match it but my OCD kicked in so just touched up the swr with the 7300 internal tuner. 73
Tim would this be a 49:1 unun? I'm having loads of issues with my so called multi band end fed antenna with a 9:1 unun. I've hooked my vna to it and none of the bands show an swr of less than 3:1. The length of the wire is 19.8 m so half wave for 40m, on the analyser it shows an swr of 10:1 for 7mhz! Any thoughts?
If it’s a half wave then a 9:1 won’t bring into a useable swr. You can use a 49:1 and that gives you 40 20 15 10m. Or as I used here a monoband version which is matched via an LC network but only for the Halfwave length band .. in my case 40m. So a 49:1 cut to about 20m long will do this yes.
@paulkazjack You should NOT use half or quarter wave length (or any other resonant length) for your end fed random wire antenna with a 9:1 UnUn. Depending on the space you have for the deployment of the wire you could search for article "Best random wire antenna lengths" by VE3EED (SK) and decide what suits your needs.
@@paulkazjack No problem. I forgot to mention you need ground/counterpoise for this type of antenna. It gives me completely different readings on VNA with and without the ground. Dips are on different frequencies if it is not grounded. Also, reception is better when it is grounded. At this moment my 9:1 unun is wound on T130-2 so it is not that great on 160, 80 and on 40 SWR is around 2.7 to 3.1. On 20m it is 1.6 so I don't even need to turn on the tuner and leave it bypassed (it is great on 10m but the band is dead). In the next few days I will make a new unun on T240-43 and stretch a longer wire and see what will happen with 160, 80 and 40m.
Just to confirm the SWR was 1.7-1.9:1 from 7100 to 7200 so useable and only touched up with the IC 7300’s internal ATU.

Thanks Victor. That sounds like a great solution! 73

Thanks Syd you sounded great!
Thnx Tim i been tossing n turning with the idea of a low wire in my garden for months,just the inspiration i needed in this video
That’s great Brian give it a go 73
Great work Tim i am going to have a go at this next week (waiting for antenna wire delivery) these vids are brilliant for us newbies de 73s M7CHA
Thanks Mark .. good luck with the installation 73

Nice bit Tim and thanks for making. AD0NC Minneapolis MN. USA.
Thanks!
Howdy Tim! With a low antenna like this and on this band, you will get good NVIS, up to about 1000Kms... Nicely done!
Thanks Peter! 73
Excellent video Tim. That antenna certainly works! Looking forward to some Inter G propagation on 40M. 73 Chris M0RSF
Yes it did very well Chris, hope to with you on 40 soon. 73
Hmmm I have been trying to do the same but for 160mtrs !!! Not a great deal of success as yet...
Great video as usual Tim.
Thanks Roly! 73
Another good video Tim 👍
Thanks Mark 73
Thanks for the video Tim, is the IC 7300 your home rig ? I been thinking about NVIS for 80 m and locate comms. Thanks again !
Hi Andy yes it is my home rig. I also use the ft891 for mobile and occasional home use. Glad you liked the video 73
Tnx Tim. A bit of fame. You were booming here. ON8EI John.
Likewise John .. good to work you again on 40.
Thanks Tim. Off to get a coil of wire tomorrow 😁
Brilliant!! Let me know how you get on

wow, does your coax to your ic7300 is grounded? this is interesting
Not grounded but good to have a choke about 2m from the transformer when using 40m just to stop any common mode making its way back to the station.
Tim would this be a 49:1 unun? I'm having loads of issues with my so called multi band end fed antenna with a 9:1 unun. I've hooked my vna to it and none of the bands show an swr of less than 3:1.

I have tried several times to e-mail you without success,
Are you using my email on QRZ? It does work as I’ve had other emails to which I have responded? Does it say undeliverable?
