Featuring a two-position antenna switch and 4,000 memory presets, it delivers near-instant tuning and seamless band changes. Its intuitive LED bargraph provides real-time RF power and SWR feedback, while ultra-fast tuning cycles keep you connected without interruption. Compact and durable, this tuner is optimized for modern transceivers and digital modes, backed by a 2-year warranty for reliable performance. ## Description The LDG AT-200ProII is a general purpose automatic tuner suitable for any amateur application. It covers 1.8-54 MHz, and features a two-position antenna switch allowing instant switching between two antennas. The AT-200ProII requires just 5 watts for operation but will handle up to 250 watts, making it ideal for the new generation of higher powered transceivers, or for QRP operations that sometimes use a small amplifier. Like most LDG tuners the AT-200ProII operates automatically, beginning a tuning cycle whenever the SWR exceeds a preset limit. The AT-200ProII also features LDG’s advanced memory tuning, providing 2,000 memory locations; when tuning near a previously used frequency it will recall the settings for nearly instant tuning. It learns your favorite frequencies and bands as you use it. You can also start a tuning cycle manually whenever necessary. Large, easy-to-read LED bargraphs show forward and reverse power power in peak or average mode, and SWR. Two power scales are provided: 25 watts and 250 watts. The bargraphs also indicate tuner status and input confirmations. The AT-200ProII uses LDG’s state-of-the-art, processor-controlled Switched-L tuning network. It will match dipoles, verticals, inverted-Vees or virtually any coax-fed antenna. The LDG AT-200ProII is designed for this new generation of rig. It's specifically recommended for Ten-Tec and tube radios. Many QRP operators have a small 100-150 watt amplifier for times when you need a few more S-units. The AT-200II is ideal for this kind of operation; it’s minimum required power is only 5 watts, but it will handle the higher power as well. You can also use the AT-200ProII with longwires, random wires and antennas fed with ladder line with the optional LDG balun. Operation couldn’t be simpler: while transmitting a carrier, just press the Tune button. An automatic tuning cycle will begin, a few seconds later the tuner will be set at the lowest SWR (almost instant for frequencies stored in memory). ## Features - 5 to 250 watts SSB and CW. 100 watts on 6M. 75 watts with PSK or digital modes. - Easy to read LED bargraph display for RF power, SWR and status - LEDs for Antenna Position and Bypass - 4,000 memories (2000 for each antenna) for instantaneous band changing - Two position antenna switch with memories for four antennas on each position - Tuning time: 0.5 to 6 seconds full tune, < 0.1 second memory tune - Built in frequency counter for memory operation - Frequency coverage: 1.8 to 54.0 MHz. - Tunes 6 to 800 ohm loads (16 to 150 ohms on 6M), 6 to 3600 ohms with optional 4:1 Balun (LDG RBA 4-1) - For Dipoles, Verticals, Vees, Beams or and Coax Fed Antenna - Includes 6' DC power cable - Enclosure: 9.5D x 7.1W x 2.0H inches - Weight: 2 pounds ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00KH6266S | | AntennaDescription | Radio | | Best Sellers Rank | #2,651 in Radio Antennas | | Brand | LDG Electronics | | Color | Black | | Compatible Devices | Laptop, Radio, Desktop, Tablet, Smartphone | | Connectivity Technology | Radio Frequency | | Connector Type | RCA | | Customer Reviews | 4.6 out of 5 stars 45 Reviews | | Item Dimensions L x W x H | 9.5"L x 7.1"W x 2"H | | Item Weight | 2 pounds | | Manufacturer | LDG Electronics | | Mfr Part Number | AT-200PROII | | Model Number | AT-200PROII | | Number of Items | 1 | | Product Dimensions | 9.5"L x 7.1"W x 2"H | | Tuner Type | Digital | | UPC | 702685258508 | | Unit Count | 1 Count | ## Product Details - **Brand:** LDG Electronics - **Color:** Black - **Compatible Devices:** Laptop, Radio, Desktop, Tablet, Smartphone - **Connectivity Technology:** Radio Frequency - **Connector Type:** RCA ## Images ![AT-200PROII LDG Electronics Automatic Antenna Tuner 1.8-54 MHz, 5-250 Watts SSB and CW. 100 watts on 6M. 75 watts with PSK or Digital Modes. 2 Year Warranty - Image 1](https://m.media-amazon.com/images/I/51TesEge2gL.jpg) ## Frequently Bought Together - AT-200PROII LDG Electronics Automatic Antenna Tuner 1.8-54 MHz, 5-250 Watts SSB and CW. 100 watts on 6M. 75 watts with PSK or Digital Modes. 2 Year Warranty - RFAdapter RG8x Jumper Cable, 2 Pack 2ft CB Coax Cable PL259 UHF Connector 50 ohm Low Loss for Ham Radio, Antenna Analyzer, Dummy Load and SWR Meter --- ## 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.it/products/6642561-at-200proii-ldg-electronics-automatic-antenna-tuner-1-8-54](https://www.desertcart.it/products/6642561-at-200proii-ldg-electronics-automatic-antenna-tuner-1-8-54) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-09-28*
