Vhf Dipole Antenna, It describes the distribution of charge within the antenna. 1 x FM dipole radio antenna. Now con-nection to normal coax is easily made below the antenna. With an emphasis on affordability and simplicity, it explains the basics without overwhelming technical details. . 1x flexible tripod mount with 1/4Inch male screw. Wideband antennas for SDR, radio monitoring, jamming, and other applications on VHF/UHF band 20 - 512 MHz. Connectors 5. Your first antenna – the half-wave dipole Many hams’ first choice of antenna is a half-wave dipole. Import Duties. It’s a great ‘ No-Fuss ‘ affair that even the most inexperienced user can construct. It works with free software like SDR# on Windows or SDR Touch on Android, and even runs on Raspberry Pi for portable setups. I enjoy building antennas. Tape measure 10. "Higher gain" in this case means that the antenna radiates less energy at higher and lower elevation angles and more in the horizontal directions. This article serves as a beginner-friendly guide to constructing a simple VHF dipole antenna for 2 meters, perfect for novices in the hobby. Material: PE transparent coat. Frequency range: 70~108/520-1710MHz. InnovAntennas VHF UHF Plus Log Periodic Dipole Array Antennas 18486-0117 Antenna, Log Periodic Dipole Array, 17 Element, VHF-UHF-SHF, 100 to 1300MHz, 5. This type of dipole antenna is resonant, operating at a point where it is an electrical half wavelength long. 5 inch OD round members. We offer an innovative lineup of in-stock, VHF / UHF Antennas including Collinear, Yagi, Exposed Dipoles, and Dipole Arrays, for a variety of applications, including military communications, trunking, Land Mobile Radio (LMR), public safety, and amateur radio. Including DX and NVIS Performance plus Pros and Cons. 1 ft. As a result, studying the antenna designs that can be used in this band is crucial. I read the article he was referring These long telescopic antennas cover VHF to UHF. This gain its not something "exotic" if the antenna compares with a 2 x 5/8 or a 3 x 5/8 "Lamda" Commercial antenna, which it has about a similar gain. Our Base Station product offering consists of a wide range of antenna types and features to meet the exact needs of our customers The most common form of log-periodic antenna is the log-periodic dipole array or LPDA, The LPDA consists of a number of half-wave dipole driven elements of gradually increasing length, each consisting of a pair of metal rods. Wire stripper 8. Build a high gain bi-square antenna for higher HF bands. To form the rigid coax section, you’ll need to insulate the center conductor (lower part of the stainless whip) from the lamp tubing with Here are the best HF Antennas from Vertical, Dipole, MagLoop or Magnetic Loop. Power drill 6. We offer a new series of in-stock, VHF / UHF Antennas including Exposed Dipoles and Dipole Arrays, Collinear and Yagi Antennas for Land Mobile Radio (LMR), public safety, military communications, trunking and amateur radio applications. But don’t be misled – just because they are easy to make doesn’t mean they don’t work well. Omni John E. Produced to the highest quality standards these robust antenna designs will ensure reliable operation in harsh environmental conditions. These antennas are designed to radiate electromagnetic waves efficiently. Multiple dipoles can be mounted on a tower and connected with a phasing harness to form a high gain, stacked array. Maximum power input is 500 watts. Omnidirectional antennas for professional radio applications, available as single antenna, as well as system of 2 or 4 antennas, 138-174MHz or 406-512MHz Dipole and V-Dipole hf antennas are commonly used in radio frequency communication. This four-bay exposed dipole VHF antenna can be arranged in an offset pattern producing a higher gain of 9 dB. Sinclair Technologies Sinclair Technologies is recognized globally as an industry leader in the design and manufacture of high quality base station antennas meeting the needs of the most demanding applications in public safety, government, and military applications. 138-174 Dual Dipole,1/4W Comprod VHF exposed, dual dipole antennas have internal cable and fixed 1/4 wave dipole to mast spacing. THE (VHF) DIPOLE ANTENNA At VHF and UHF, most antenna systems are derived from the dipole or its complement, the slot antenna. Both the portable VHF UHF or HF end fed, or dipole antennas, are fairly efficient and most often are easy to setup for field day or other remote operations. Wrenches Nov 13, 2025 · The ZED Dipole Antenna is an innovative, practical, and easy-to-build antenna design popular among VHF/UHF hobbyists. Another option for a base station antenna is the dipole antenna. 1. Boom, Horiz.
