Sirio New Vector 4000 Tunable Antenna Big Vertical, Big Signal, great for DX

New Vector 4000 under 10 m/sec wind - YouTube. Video will open in a new window. How the Vector-4000 Ride's the Storm 09/01/15 - YouTube. Excellent Reports on Sirio Vector 4000 CB/10M Base Antenna!

Best vertical I have ever used on 10m and i have tried a lot of them. This is a close copy of the Avanti and they had a great design with the original sigma4.

I would advise everyone to guy this antenna about half way up with nylon rope because it does sway a lot in any bit of wind. High Gain 3/4 wave 10/11m vertical antenna. Dec 20, 2013 03:01.

Send this review to a friend. Excellent antenna but needs some mods. Time owned: 6 to 12 months. Like a few others here, I used this during my 11 meter days. It would put a signal where other antennas couldn't. This antenna features a very low angle of radiation, which is what it's all about with a vertical. I'd give it a 5 but the mechanical construction of the main element needs some modification. Then place stainless steel hose clamps near the top of the slits and tighten.

Use 2 clamps at each position with one right under the other. You'll need to find clamps of several different sizes, as the vertical tubing changes size from about 1/2 inch to almost 2 1/2 inches.

This really reinforces that piece and helps it handle wind. I had 2 of these in about a 1 year period and they really work. I can remember watching one dancing in the winter winds and seeing the upper half perpendicular to the lower half...

And then go right back to vertical. Thanks for the tip Ronny. Jun 25, 2012 03:49.

Time owned: 3 to 6 months. En mas de 20 años de uso, no he encontrado otra vertical para 28Mhz que rinda como esta, y el precio asequible por la calidad, totalmente recomendable Saludos Ramon EA3TI.

Would have been rated a 5 if not for its susceptibility to high winds. Sep 29, 2008 19:23. Time owned: more than 12 months. I had one of these back in 1995 or so when i did the CB thing, and it was up about 30' on a roof top.

The antenna was about 32' long overall, a tad bit longer than the Avanti Sigma 4 but it performed just like it. The antenna tuned all of 11 meters with a flat SWR. I never had an isssue with the antenna.

Funny thing is i also ran an Avanti Moonraker 4 and quite a few locals claimed the onmi and the beam had the same S units! Who knows, i might use it on 10 meters. Feb 8, 2008 14:13. A variation of the Avanti Sigma four design except the Vector 4000 is stretched to 7/8wl. One great performing antenna with a slight edge on the 827, but not as useable on other bands due to the nature of the beast.

It's as delicate as Chantilly Lace, it will not survive long in gale force winds, the second and third top elements usually snap first being far too long to survive. It is possible to modify and engineer for greater toughness and wind survival, but, given the limited useability on other bands, it is not practical, being something you might do to prove a point. Great eleven/ten metre antenna, the performance is highly recommended but not the build quality!

I bought the sirio vector 4000 about one month ago. I can say that the antenna is worth every penny. The only thing that I have to complain about is the setup. Other than that the antenna is perfect. Aug 19, 2006 05:08.

Hallo i have just bought my new SIRIO VECTOR 4000 antenna and i sware i have better resultat then my colegs from radio amater club with there yagi 7element antenna on simple cb frequencies with an old amp "eltelco norge" from italy with one valve 6LQ6 in and about 50-70watts on the end. Dawn i love to work the far out stations and with single output of 5-7watt i copy stations with ground wawe far as 90km from me with no problems!!! Amaising i even push out 2watt in contact with station far as 1740KM WOOOUW!!!

I could not beleve that raport on other side is 3-5 clear and crispy on 14 stations? Man im sorry but i love this antenna and im just fishing on cb freq foor a contact. With 4watts if freq is not too busy i call just ones and "bingo" amaising and with 50watts raports are 5-8 5-9+ waaauw!!! Im sorry gys but this is an radar and not just an antenna...

Oct 7, 2005 00:23. I have owned one of these in the past, its basically a Sigma IV clone.

Works exceptionally well on 10m, outperforming everything I could check it against, however I have never "back to back" tested it with the Sirio 827, which on paper should be better. I have never tried it on the other bands, should tune 10-20 with an ATU so would be interested in trying that. Thinking of getting one for portable work!! It will look good strapped to the back of the car!!

They say beauty is in the eye of the beholder, and to me these things look amazing!! Jun 4, 2004 06:02. Any DX on 10m that was heard/worked on my long boom monoband 4 element yagi, could be heard/worked on my Vector 4000.

I was even working other UK stations over 75 miles away under flat conditions. Performance wise, better than any other 10m verical I've tried.

I might think twice if I lived in a windy area though.. The classic Vector 4000 base antenna has now been upgraded and this very latest version has just arrived, if you are looking for reliable long distance contacts, the New Vector 4000 is for you!

Not to be confused with the early model being offered elsewhere this is the. Version of the Sirio Vector 4000 announced earlier this year. The Sirio Vector 4000 is an Avanti Sigma 4 style base antenna, 3/4 wave with cone shaped basket. Main changes are the lowered basket which gives the antenna greater stability and improved DX performance and the cage type "egg whisk" top whip.

Gamma match tuning allows precise SWR tuning and the Vector 4000 is also suitable for HF use 20 - 30 MHz with an ATU. 3/4 Base Station antenna tunable from 27 to 28.5 Mhz.

Made of tellescopic anti-corodal aluminium tubes. Its long and robust whip allows perfect performances and very good connections at distances too. Tunable by whip length adjusting. Made of aluminium alloy 6063 T-832.

UP-GRADE: Lower radiation angle for the best DX, new tuning possibility. Frequency range: tunable from 27 to 28.5 MHz.

Gain: 2 dBd, 4.15 dBi. Bandwidth at SWR 2: 1400 KHz.

Power: 1000 Watts continuous, 3000 Watts (PEP) short time. Feed system / position: Gamma match / base.

Wind load / resistance: 329 N at 150 Km/h / 130 Km/h. Wind surface: 0.29 m². Mounting mast: Ø 35-42 mm. SIRIO CB/10 Meter Base Antenna Compairsion Chart -- by DNJ Radio.
