Comet Antennas No-Hole Fender Brackets
Comet No-Hole Fender Brackets are vehicle-specific truck and SUV mobile antenna brackets that mount without drilling. Unlike lip-mounts that use set screws and penetrate the paint; these brackets use bolts that already exist on your fender. Due to the particular vehicle-specific angles necessary to form these brackets, almost all are designed for the driver's side only. (There are only a few new right fender mounts!) By using an existing fender bolt, the bracket extends between the hood and fender gap. The mounted antenna sits vertically, along the side of the hood. A 3/4 in. hole in the bracket accepts the standard NMO connector and cable assembly. You may also use these brackets to attach an antenna that has a UHF mount. Simply choose a Comet UHF mount cable assembly; they include a large washer and jam nuts to keep the 5/8 in. diameter UHF connector from falling through the 3/4 in. hole in the bracket. NOTE: * Coaxial cable and base mount assemblies are not included with these brackets. * Not suitable for larger antennas which require the use of a heavy duty bracket. These clever mounting brackets provide a stable antenna platform without drilling holes in your vehicle. Order your Comet No-Hole Fender Brackets from DX Engineering and enjoy mobile operating again!

Alpha Delta Antenna Hardware Kits
Alpha Delta Antenna Hardware Kits contain one DELTA-C Center Insulator, antenna connection hardware, one model SEP arc-plug static electricity protector that is installed on the back of the DELTA-C, and two model DELTA-CIN End Insulators. These kits are a great way to build wire antennas! The antenna hardware is constructed using Alpha Delta's exclusive Model Delta-C Center Insulators and model CIN End Insulators. They're molded from Deltalloy, an extremely tough and durable plastic specifically blended to withstand sunlight and extreme weather conditions. An SO-239 connector is provided for a direct connection to the PL-259 on your coaxial cable. Or, a ladder-line balanced feedline may be connected directly to the dipole wire ends. If a balanced feedline is used with an antenna tuner in non-resonant applications, the SEP arc-plug must be removed to prevent the "false triggering" of the gas tube. The ALP-SEP arc-plug static electricity protector is a special gas tube component designed to bleed off slow-rising static electricity buildup generated by thunderstorms, high-wind driven snow, sand, or even a harmless looking cloudy day. These static charges have been measured to several thousand volts and can damage or destroy sensitive components in receivers' or transceivers' front-end circuitry. Note: When the "Documentation" tab is available, please look at the associated files for additional product information. For wire antenna kits with a little something extra, order Alpha Delta Antenna Hardware Kits from DX Engineering!

Antennas with the 'fold-over' feature offer yet another solution! All mobile antennas represent some sort of compromise. The diversity of styles and features offered by these dual-band mobile antennas allow you to choose what the compromises will be. You may make choices of gain, size, mounting, power rating, connectivity, price, and even color! With so many choices available, your problem won't be finding a suitable antenna; it will be finding just one! No matter which antenna you choose, there will be one no-compromise aspect: Every antenna will feature the same fine quality you have come to expect from Diamond Antenna Dual-Band Mobile Antennas!

KiwiSDR V2 SDR Protection Circuit
The KiwiSDR V2 SDR Protection Circuit is designed to safeguard KiwiSDR receivers—and virtually any other SDR—from the most common and costly sources of front end damage. Many KiwiSDR owners have experienced failures caused by nearby lightning storms, transmitting into an antenna positioned too close to the KiwiSDR antenna, or accidentally transmitting directly into the receiver. The original V1 protection circuit provided solid protection against static discharge and nearby lightning, but it did not always survive accidental high power RF transmission. The V2 design directly addresses this. The upgraded V2 unit adds a replaceable 100 mA fast blow fuse, providing an additional sacrificial layer of defense for your receiver. A spare fuse is included in a small plastic bag—keep it safe, as 100 mA 1808 fast blow fuses are not easy to source. The protection circuit is housed under a secure 3D printed cover held in place with a 1.4 mm screw for easy access.
