Ham radio: Easy and Great Performing vertical for 10 & 15m without radials

A quick look at the super easy to deploy end fed half wave for 10 and 15 metres.
Less than 6m long and therefore a great portable option. No radials needed.

Nice one looking forward for the next video Tim.

Thank you!

I made a 49:1 for 10/11m using the same idea, but without the 15m trap, I got near 1:101 SWR on it, and I ran 250w into on 27Mhz at 1:1.2. It worked fine, but having left it erected outside for 2 months now, it's displaying almost 4:1 SWR. Either the wire has broken down (unlikely) or the 49:1 isn't 49:1'ing anymore. I still have to drop it down and check it, but it's been raining on and off here for over a week and I'm just not going to drop a10m pole in the rain....decent antenna when it's working correctly, I made FT8 contacts on at 20w on 10m to the USA, Nicaragua, Japan and 3 or four more DXCC listed countries in less than 2 days. And my QTH isn't anything special.

Good stuff!

Hi Tim , m currently building a fan dipole with 2 reflectors for 10m and 20m in a horizontal plane is the relector above or below the fan dipole

[@timg5tm941]

Sounds a good project

[@ammocraft]

Where did you buy the traps from, out of interest? Asking as also time poor, but have been wanting to try a 20/17/15m version of this for some time.

[@timg5tm941]

Sadly the guy who made them isn’t anymore

[@johnnorth9355]

Ah I get the Idea Tim but I am resisting pressure to get my single vertical down so sticking another up would be like a red rag to bulls ! Horizontal wire dipoles with trapped ends (and maybe a right angle at the middle connector ) is my next counter offensive 🙂.

[@timg5tm941]

Good work John!

Being an EFHW, the feedpoint is of course high voltage (high impedance), so a bit of separation from 'anything' (like the earth, even in that orientation) would be a good thing. Also, if you don't have a counterpoise, then your feedline will be the counterpoise and thus tend to have currents on the outside. (Edit: a mounting point conductive ground stake is fine! High Z low currents as we all know.) But otherwise a very good design concept.

[@timg5tm941]

Never experienced any issues with stray rf running 100w.

[@MM0OPXFieldRadio]

Excellent mate. Next couple of weeks I need to get on making these traps myself.

[@timg5tm941]

Nice one Colin!

[@rmonsipapa]

Where did you buy the traps?

[@timg5tm941]

Sadly the chap who made them isn’t doing do anymore

[@harryszwergstatt2879]

Nice Antenna👍

[@timg5tm941]

Thanks!

[@izzetmuroz]

Keep up the good work mate...

[@timg5tm941]

Thanks!

[@LB4FH]

Looks like a nice one, gotta try this out

[@timg5tm941]

Go for it!

[@RonanCantwell]

Nice work Tim. This'll be a great little antenna for daytime portable use. Looking forward to seeing how it performs in combat. 👍👍

[@timg5tm941]

Thanks Ronan!

[@32_bits]

Another interesting video. BTW is that a 405 line post WWII TV behind you :-)

[@timg5tm941]

No it’s a late 1990’s CRT

[@MikeN2MAK]

Looks like a fun one!

[@timg5tm941]

Thanks Mike!

[@M7BCN]

Nice one Tim.
