A "random wire" is more typically what people think about when they say "long wire". This is a rare case where a compromise turns out to be the very best solution! Spiderbeam, one of the industry's leaders in providing wire antenna solutions for use with fiberglass poles, recommends two wire sizes for use with its poles: AWG-18 and AWG-26. Did I receive bad advice? I didn't know what questions to ask. This is only partly the case with these Hari long-wire antennas, in order to keep the length in a manageable size. These things don't happen because copper wire doesn't corrode in any practical way for ham antenna purposes. For instance, it can match a 23 feet long wire antenna over 1. (Don Keith, N4KC is a long-time active Ham and former broadcaster. Understanding Shortwave Long Wire Antennas. Technically a true "longwire" needs to be at least one wavelength long, but Backyard Multi-Band Wire HF Antennas L. Simple Construction of Wire Antennas. The long wire, in terms of wavelength, was a popular antenna for trans-Atlantic radio telegraph links. A shortwave long wire antenna is a simple and inexpensive HAM RAdio solutions. Later I received a ham license in 2000 and contacted approximately 130 different countries. DX Engineering carries wire antennas and universal wire antenna kits from the most-trusted ham radio brands. Wire antennas are the most popular choice as they are easy to install and cost For years, the ARRL VHF Manual had charts for Vee beams and Rhombics for 6 and 2 meters. Most simply used wire antennas and matched them the best they could, usually with the output circuitry in their transmitters. B. Types of Indoor HF Ham Radio Antennas . The G4YKB Longwire The G4YKB Longwire is a longwire Antenna in name only, to be used with an ATU to enable fixed station operating with restricted space, or portable users access to Ideally the wire element should be run in a straight line however where this is not possible it will function in Ham radio enthusiasts continually seek ways to improve their communication range and clarity. This antenna is capable of operating on all HF One type that I have found to be highly effective is the long wire antenna. Long wire or random wire antennas are very simple antennas. Supplies (see the Long Wire Directional The best installation for me would be to wrap it around under the eaves of a storage shed or between trees and taking a couple of turns I started experimenting with long wire antennas when I was a shortwave listener in the early 1990s. LW-40 long wire HF multiband antenna 160m to 6m 500W PEP . to/3A5NfJv. There are other considerations (wire material, wire gauge, coating, etc. A wire more than 1wl long exhibits gain off the end of the wire (not broad side like a dipole) and narrow beam width. 6-30MHz. This is a great antenna for shortwave receivers, as well as HF ham radio with an ante I have purchased a Palstar R30A receiver and want the best possible reception. The ground wire should go to a cold-water pipe or an actual earth ground.
