3el AIS Antenna, AIS Yagi, Marine Band Yagi Antenna, AIS Marine band antenna
Ask a question about this product. A 3 LFA Yagi for AIS Marine usage - Hear what you cannot hear right now! No matching devices or matching related losses! If you want the best in AIS performance, it needs to be a computer optimised Beam antenna you use! Vertical antennas can not give the same focused combination of beamwidth and gain that a Computer optimised vertical can.
Below is a report of usage from a UK listener. Thought you might like to know that the stacked array has now been installed. It is mounted on a 15ft pole, points in a southeasterly direction and is performingly extremely well. The adjustment to the trombones to get a low SWR was minimal and was achieved by pointing the array vertically skywards and it hasn't changed now it is in position, currently reading less than 1.1 around 156 Mc/s. On the receive side, there is excellent reception across the band from 156 to 162 mc/s with data pulses being heard on 161.975 and 162.025 which are the two channels for AIS. Incidently, I just happened to switch to airband and was surprised to find how good reception is there also. In short, I'm very happy with the product, both from the quality/performance and also the one to one advice in the first place. Many thanks and kind regards. I'm still very satisfied with my 3 el- AIS antenna, performing far better than excpected. I live in a fjord with high mountains and limited line-of-sight. My previous range record with the 5 feet vessel antenna was almost 10 nm. Now I'm recieving AIS signals from vessels at the coastline, longest range until now is 55 nm. 2 x 3el AIS Yagis installed at the station of Norman, G4YXX. The coverage Norman now has from his 2 antennas. Marine grade Stainless Steel Fittings (Except Mast clamp). Thick 3/8'' elements (1/2'' loop sections). Mill finished boom and elements for highest levels of accuracy. Gain 10m above ground: 14.37dBi. SWR: Below 2.5:1 from 156MHz to 163MHz. Manufactured the right way, not the cheapest way! Where possible marine grade stainless steel components are used. We will always go out of our way to source the product you are looking for. InnovAntennas use the very latest software design tools and optimisation methods (Particle Swarm Optimisation) in order to achieve the very highest possible performance characteristics. Other companies just don't publish polar plots and with good reason! We are proud at just how good our antennas look and perform and for this reason, azimuth, elevation and SWR plots for each and every antenna are published. We can also accept collection for most items. Address UK: InnovAntennas (behind Waters & Stanton) 22 Main Road, Hockley Essex SS5 4QS UK.
