#1 TEST: mini 9:1 UnUn Random Wire home made Antenna (part 2) 

Thank you Richard. Yes we live in a small city on the edge of a large Carpathian arc: upload.wikimedia.org/wikipedia/commons/thumb/5/5a/Carpathians_dem.jpg/270px-Carpathians_dem.jpg Its a large mountain belt with forests in the central and central east of Europe. The place where I had been is a hunting tower located here: goo.gl/maps/oRqoGDPRpuG2 Have a nice day! 73 Paul

ja dakujem tiez za pozretie! Uvital by som aj lepsie podmienky na KV :-) ale v tomto obdobi asi marne :-) Prajem ti vela stastia! 73 Palo OM0ET

Yes Scott. I had counted with not-success too...that's the QRP world :-) But this is so interesting on this activity. Never know how it will work hihi and we can still make improvements to be better next time ;-)

that sounds great! This guy what I worked in this video was active flora fauna so SOTA cold be great too ;-) 73 Paul

Thank you 😊

Thank you for the kind comment Jonathan 😊 it's a QRP world 😁 I believe in next success 👍73 and have a nice day! Paul

@@OM0ET I'm also a happy x5105 owner and also trying to find the most minimal solution for hiking etc. I've only had it for a week and did one test, Inverted V vs No-balun random wire. Inverted V won by a long way... So now I'm looking at the more traditional end fed approaches (half wave with balun etc). Would love to see you test a known antenna vs your experiments.

Thank you Preston :-) What case do you mean - UnUn plastic case?

Yeah, in some case we can use the coax feed line as the counterpoise. :-)

Thank you very much for watching and nice comment Preston! The pouch I use is from my TECSUN PL600 shortwave SSB receiver. Is funny how perfectly fits for X5105 :-D You don't need drill in to your radio! There is more easier way how to do. You will need T BNC connector like this: www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=T+bnc+connector&_sacat=0 One end connect to antenna and second one to the ground wire - but without center pin in connector of course! Ground wire will be connected only to the shield or body of the BNC connector. I have done this already. It works great. You will not loose warranty. 73 Paul

Very nice! Good DX even with so poor propagation like this days is. With 100W?

Bill, I believe you will need a 1:94 with EFHW. 1:9 will work with a (not really (check the tables)) random wire-----------. Edit 1:49

:-D ...btw. I met 3 young deers on my way up there but pity is that I hadn't much time to record them on camera. Next I will use better grounding on my antenna and hopefully the propagations will be better :-) 73 Paul

@@OM0ET Yeah, it's been getting warmer, but it appears that the ionosphere didn't quite receive the memo yet. A critical frequency of merely 2.5 Mhz or so well after sunrise, like it has been lately can really ruin a QRP wire enthusiast's day. You get this tiny window in the afternoon to play a bit on 40 meters, and that's about it. Unless you get off the ground to get a flatter takeoff angle, something you don't really have much control over when portable, you're simply screwed in conditions like that,and I am not sure the owner would have appreciated you attaching a mast to his treestand to raise your antenna's feedpoint. Could have been an entertaining video, though. You don't get to watch ham operators dodging shotgun pellets very often. ;)

​@@KannixKostnix :-D :-D Thank you for the nice comment! I believe in better futures :-) and hope for better propagations soon. In summer will be Es so it could be better for QRP. 73 Paul

Both toroids gave passed 450 ohm test, but material is not good. I recommend FT50-43.

I have got this pouch with my TECSUN PL600 receiver. It fits perfectly on the X5105 too :D

OM0ET I have one of those. Thank you. I think people would love to have a piece of equipment with your call sign on it.

@@tommycheshire5508 thanks! 😊

Thank you :) yes I will... I used 17,678m long radiator/58ft. Maybe I should try 45,110m/148ft and good counterpoise or better grounding :-) 73 Paul

LOL :-) I like that place, I met also 3 young deers...my new subscribers probably :-D hihi 73 and thanks for comment! 73 Paul

Zdravim. Jeden balun som v piatok posielal do Kanady a vyšlo ho to na 30€ s poštovným. 🙂

Presnejsie za 32€

yes next time I will make a better grounding and hopefully it will work better :-)

OM0ET surely a simple mod to add a ground tap and you could keep the gorgeous tiny form factor

It's an older video. Things has changed. Today I use only 17.6m long wire. The base version is 44m long wire, 300W.

It's the QRP world 😁 I want to made 49:1 transformer and half wave wire. It don't need ground and has better efficiency. I am curious how this will work 😊 But all depends on propagations... 73 Paul

@@OM0ET Oh yes your right it's a 49:1 he made but it's basically similar in deisgn just a few more windings! :) And then a collection of wires tuned for each band.

thanks I will try 27m too ;-)

Thank you. Yesterday we were on the Field day with this antenna and 1.5m above the ground hight we made QSO to Puerto Rico in central america on 50W on 20m band! 😃 Thanks for comment and 73!

A quarter-wave counterpoise for the band in use will solve all your SWR problems. Thanks for the video and vy 73 from G4FSN, near Manchester UK.

@@ericwalton1492 Usually, you can choke the feedline 1/4 wave downline and let the coaxial act as counterpoise. Vinyl jacket has 90%VP. You must set the choke 9 meters down, in 40 meters. Regards. LU1AR

@@edgardomaffia5356 That's true, what you say, but I just have about four different counterpoises in my bag, and connect the one you want to the earthing bolt on my rig. I think counterpoises are better run along the ground, as long as you position them where no-one can trip over them!

The Alinco DR135MKII is a VHF transceiver so no, it is not for your transceiver. For VHF radios are recommended the vertical antennas or directive beam antennas - Yagi's for example ;-) 73, Paul

yes it is possible. I agree. If so, would be also easier to ground this antenna. Shame was raining during this test and I had to get cover at this cabin and transmitting from there.

Yes

I am not selling these due to lack of the small toroids. 🙂

@@OM0ET Yea... no offense - kinda like doing show and tell - and getting everyone excited with a jab in the side - that yea.. .I have this but you can't - lol Sorry just saying. no worries - though I saw another channel that had a spark plug like balun that was being offered for sell. =

Sorry but showing things on my channel doesn't means automatically I am selling this things 🙂

That is a good point, but not everyone has portable transceiver with ATU :-) In my videos I experiment with antennas which no need ATUs. ;-) My next try will be 49:1 transformer and half wave wire. 73 Paul
