SIRIO SY27-3 10/11m 3 Element Yagi/Beam Antenna,Unboxing & Assembly

[@24nov67]

had the four element version 36ft in the air since 2015 despite buying it in 2009. once you work the flatside you'll never go back to dxing with a vertical as it'll hear stations that wouldn't even register on a vertical

[@gtretroworld]

Yeah i have been finding this thing has some serious ears,hopefully the bands will pick up shortly to get the best out if it.Thanks for visiting.

[@dannystephenson4957]

Good info great video, I'd be more inclined to slide the end tubes inside each element and drill new holes for the band you want to use it on rather than sawing the tubes down - I'm sure that would work too?

[@gtretroworld]

Thanks…Yeah that would work fine,just remember to take your time getting the measurements right as these work really well if set up correctly…Thanks for visiting

[@dannystephenson4957]

@gtretroworld Thanks for the advice all the best.

[@ke5cos]

Just had the SY27-4 delivered and was wondering how broad banded it would be from a planned 28.400 mhz set up. The SWR measurements you provided answered my question before I even put mine together. Thank you for taking the time and effort to provide this information on your set-up of the antenna. I'm looking forward to getting mine up in the air. Great video! 73.

[@gtretroworld]

The Bandwidth with the 4 Element is a bit narrower than the 3 but it will cover all the 10m band without any problem whatsoever.. I was actually going to try the 4 element myself but i am hankering for a Quad next, maybe someday i will try it though.

[@jamespuckett6457]

I have a Sirio 10/11Mhz vertical I put up a couple months ago. I have it tuned to the 10m band and have been extremely impressed with its performance. It is well made and was easy to put together. Now I may have to try the yagi antenna.

[@gtretroworld]

This really is a great antenna and isn’t overly big or expensive.Im tempted to try the 4 element version in near future with a similar video.

[@harrybatt998]

Hello, Great tutorial. I've just bought this, and I'm about ready to construct it. With the elements cut to 27.5 as you have, is it possible to alter the Gamma match to get a SWR lower than 1.5:1 as you have, please? I do most of my operating between 27.400 - 27.600, so I would ideally want my SWR at 1.1:1 at 27.500. Many thanks in advance.

[@gtretroworld]

@@harrybatt998 Yes you should be able to get it down a bit more if you only want that narrow bandwidth , unsure about 1.1 though, just take your time as it is quite twitchy.

[@stephengunrunnerhanson3550]

A very nice antenna shrink fit on all the joins and it will not let any water get in

[@gtretroworld]

I was just going to use self amalgamating tape but yeah that could be a plan in some areas.I still haven’t settled on a coax choice yet,that is just mini 8 from a roll i had from the 90’s.

[@stephengunrunnerhanson3550]

I use the same it's all right does formy run from antenna and into my bungalow and into my radio room it's ok goes around sharp bends easily.

[@Al.26TC101]

Looks a very similar build to my di-pole, but suggest you seal up the connecting parts as I had bad water ingress, so used some aluminium grease and amalgamating tape, on each connection . Nice build though.

[@gtretroworld]

Thanks AL…Yeah the whole thing wants sealing up when i finally decide on a Rotator.I know what i want but the price makes me cringe.😁

[@fourbyten5490]

I assembled & put mine up about 1 month ago & it worked very well, but recently the SWR went very high. I failed to waterproof the Gamma match tuning area where the rod goes into the other rod, and I think rain got inside due to recent bad weather. I've read a few reports of this area being susceptible. Is yours still doing OK, & did you watetproof everything, including where I mention?

[@gtretroworld]

@@fourbyten5490 I was using it for just under a year and removed it to use a home brew Quad that never materialised, However i did use self amalgamated tape on all the joints and never had an issue.

Looks great. I'm a new m7. Currently got a cb vertical cut down for 10m. I'm looking for a 10m yagi that I can put up around 25ft or so (above my roof line but not much). Would you recommend this one?

This Yagi is Superb on 10m it really is. If you end up buying one just take your time setting it up as it is so worth it. Thanks for visiting the channel.

[@jedyman]

good video, do you have good results with this antenna in DX? apparently you made the cuts for 27,500 Mhz and according to these cuts do you have a good swr on 27,500 and what is the bandwidth please I have the 4 elements but not yet assembled. 73's

[@gtretroworld]

The antenna is superb so although the 4 element with have a smaller bandwidth the extra gain should be pretty good. For 10m and let’s Say 27,385 I used the radios ATU but it was still very good.If you plan on just using it for 11m just work out the centre of where you plan on working and cut for that.My measurements and SWR readings are in the description.

[@psychobillypaul4172]

Hi gt wonder if you still have spec sheet and could you please put up the boom length and spacing between the elements I have a four but don’t have the room for it I know it’s possible to shorten just don’t know what the measurements are hope you can help me

@@DeltaXray444 I set mine for my requirements for 10/11m but it was quite a tight bandwidth, worked extremely well with a quick tune of the ATU though. I cut it for around 27.800mhz at 1.1. Unless you plan on using 10m i would drop the centre a good chunk lower. Hope this helps.

[@armanbabloyan7404]

Dear friends, I am radio amateur from Armenia, Yerevan! EK6NK. I have purchased Sirio SY-3 yagi antenna for 11/10 meters in Paris in the shop! We tuned it how it was written in instruction and it worked very well on the floor/ground by using test mast for only 2 meters height. By antenna analyser we got good conditions of antenna data like: 1,11 SWR, 52 ohm impedance, -25.3db returne loss(see attached picture). But after installation on metallic-steel roof we have very bad data, we thought it is height of antenna and we increase it from 2.10 meter from roof to 2.80 meter, but no good changes(see attched picture). Also we have second VHF/UHF antenna on the same mast with vertical polarisation higher from Sirio by 1,5 meters(see attached picture). When we rotating antenna from South to North it working better, but not so good that we prefer. What do you think? What is our mistake? What to do ? Thank you in advance for advices Best regards, 73

[@gtretroworld]

At an educated guess i would probably say the metal roof could be causing a bit of an issue but to what degree i am unsure. I am guessing the SWR is higher but is it unusable?

[@armanbabloyan7404]

@ no, it is usable with ATU but I think antenna gain is not good, that’s why I want to have good data

[@gtretroworld]

@ Could you try it up high away from the steel roof?

105/95/93mm? You couldn't change the gamma match. I have the same antenna waiting to go up

[@gtretroworld]

It really depends where you want to operate.I use this for 10/11m so decided to sort of widen its bandwidth.Cutting 93mm off the Director,95mm off the driven and 105mm off the Reflector gives these results.1.1 around 27,900/1.5 on 27,500mhz.The Gamma match will only match so much but like i say it really depends where you want to operate.I will say though it is a fantastic antenna if you take your time setting it up.

[@BigdxGunRomania]

hello, how long does it take to install this antenna? I would use it for portable

[@gtretroworld]

If you had all the elements built up you could have this up and running for portable work in 10-15 minutes. Probably the same again if you had to build the elements up.

Instead of the plastic sleeve to connect the elements would a jubilee clip do the same job

The sleeve doesn’t really do alot other than make things look neat.I suppose if you wanted to you could do away with them and the self tapping screws and use jubilee clips but you would need to cut slots on every joint.Hope this helps.

@@EdzashedFudwinkle Yeah just think before you cut but the bandwidth with mine is fine for my needs. I actually boomed into Mexico last night on AM with 25w.SWR was 2.7 but the ATU didn’t mind.I definitely didn’t expect that result at the bottom of 26mhz as it’s nowhere long enough.
