Review: Missing instructions and hardware - I can’t fault the seller for this. In fact I got the antenna days earlier than expected. Siri, on the other hand disappointed me big time… NO instruction manual of any kind were included. I had to go online and search for the manual as to trim the antenna for 10 Meter SSB. Hardware was also missing. Not enough PK screws for the elements, and hardly any 6mm grub screws for mounting to the boom… Luckily my online manual stated the size of said missing screws, and I purchased them at the local hardware store.. Antenna is simple to assemble, and VSWR is good after cutting. ## Features - Base station antennas Directional, High-gain Horizontal polarization Factory tuned at mid-band High power handling capability Elements equipped whit waterproof jointing sleeve Made of aluminium alloy 6063 T-832 - 4 elements Yagi, Directional - 26.5 ... 30 MHz Tunable, 10m-HAM - Gain: 11 dBd, 13.15 dBi - Power: 1000 Watts (CW) continuous, 3000 Watts (CW) PEP - Connector: UHF-female (SO-239) - Dimensions (approx): 5846 x 4030 x 100 mm / 19.18 x 13.22 x 0.33 ft - Weight (approx): 6100 gr / 13.45 lb ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DZN3FD7 | | Antenna | Radio | | AntennaDescription | Radio | | Best Sellers Rank | #506 in Two-Way Radio Antennas | | Brand | SIRIO antenne | | Color | black | | Customer Reviews | 4.4 out of 5 stars 18 Reviews | | Impedance | 50 Ohms | | Item Weight | 27 Pounds | | Manufacturer | Sirio Antenna | | Mfr Part Number | sirio_sy27-4 | | Model Number | sy27-4 | | Number of Channels | 1 | | Number of Items | 1 | | UPC | 016463965695 | | Unit Count | 1.0 Count | ## Product Details - **Antenna:** Radio - **Brand:** SIRIO antenne - **Color:** black - **Impedance:** 50 Ohms - **Manufacturer:** Sirio Antenna - **Number of Channels:** 1 - **Number of Items:** 1 - **UPC:** 016463965695 ## Images ![Sirio SY 27-4 4 Elements 26.5 to 30 MHz CB/10M Yagi Beam Antenna - Image 1](https://m.media-amazon.com/images/I/71tw3fqjdqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice beam *by D***S on April 17, 2026* Nice beam for the money. ### ⭐⭐⭐ Missing instructions and hardware *by S***” on April 5, 2025* I can’t fault the seller for this.

Set up was really easy. I had the antenna assembled and mounted within an hour. Adjusted the match using my Nano VNA and had a perfect mid range match. First contact was a POTA station 1705 miles away. Very happy with this antenna. I'm considering buying two more and making them a stacked array ## Frequently Bought Together - Sirio SY 27-4 4 Elements 26.5 to 30 MHz CB/10M Yagi Beam Antenna - RFAdapter RG8x Coaxial Cable 100 ft, CB Coax Cable, UHF PL259 Male to Male Low Loss CB Antenna Cables, 50 Ohm for HAM Radio, Antenna Analyzer, Dummy Load, SWR Meter - exgoofit RG8X Coaxial Cable 75FT (23m), CB Coax Cable, UHF PL259 Male to Male Coaxial Cable Connector for HAM Radio, Antenna Analyzer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/74784196-sirio-sy-27-4-4-elements-26-5-to-30](https://www.desertcart.co.uk/products/74784196-sirio-sy-27-4-4-elements-26-5-to-30) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-04*
