Free USPS shipping. International sales are welcomed and ship through the Global shipping service.The yellow information below is from the manufacturers website:There has been much written about the G5RV. Unfortunately, much of it is incorrect. The claims of most commercial antenna builders is simply fantasy. The record was set straight when the G5RV\'s developer, Louis Varney published an article in the ARRL Antenna Compendium #1. Unfortunately, most G5RV builders haven\'t paid much attention to Mr. Varney\'s article. We did!
The original G5RV is an efficient, all band, antenna. It is shorter than a full size 80 meter antenna. This makes it appealing to those who have limited space. The G5RV will give good results on most bands with minimum effort.
The RADIO WORKS\' \'NEW G5RV PLUS\'embracestwo outstanding improvementsover the many copy-cat versions of the G5RV on the market. First, I have added a Y1-5K, our precision, Current-type balun at the transition between the balanced stub and unbalanced coaxial cable feedline. The second improvement is the choice and length of matching stub and RG-8X feedline combination. The matching stub is reactive on most bands. The reactive nature of the antenna and stub makes matching difficult unless a wide range tuner is used.
After careful analysis, I changed the matching system for the best compromise on all bands. A change in stub resonance and a specific feedline length was necessary to achieve the best match on each band. Still, the match is not perfect on any band. It is lowest on 20 meters where the SWR drops to around 1.8:1 under ideal conditions. On all other bands, the SWR will be higher. Even with a slightly elevated SWR, losses in the system are low. Unless you are using a rig with tube finals which can accept a moderately high SWR, a tuner is necessary. This advice goes for any G5RV. Contrary to what many antenna makers claim, the G5RV requires a tuner unless your rig can tolerate a moderately high SWR.The Y1-5K, Current-balun keeps RF off the coax and reduces any chance of RF response problems.Combining these technical improvements with the G5RV\'s own attributes produces a very good antenna system. The RADIO WORKS\' NEW G5RV PLUS is an excellent combination of performance modifications, high quality, and high power parts.You can\'t find a G5RV that works better than this one.
The reduced size of the G5RV is one attractive feature. A second is multiband operation with coax feed. Coax is so much more convenient than ladder line or open wire. Further, most modern tuner circuits do not work well when feeding reactive, high impedance feedlines. The G5RV does not require a balanced output tuner. This means that you can use the NEW G5RV PLUS with nearly any tuner, including those neat little \'automatic tuning units\' that some rigs have. One short caveat though, the SWR may get out of the tuning range of the automatic tuners on some bands. It all depends on your particular installation.
