Comet Window Feed-Thru Jumpers

Comet Window Feed-Thru Jumpers are flexible, 50 ohm, flat feedline assemblies with SO-239 UHF female connectors at each end. They are used for routing RF through a window frame without drilling holes for the coax cable or connectors. These window-gap jumpers are almost 16 in. long and are made from copper-clad steel and PET plastic to allow for a low power transfer of RF with a nominal loss of only 0.5 dB up to 500 MHz, and they are useable up to 1300 MHz! When drilling through the wall is forbidden, or if there is no way to make a sufficient hole for your coaxial cable, then a Comet Window Feed-Thru Jumper may be the problem solver that you need! Here are the specs that will help you decide if one of these handy flat cable assemblies is right for you: * Frequency Range: DC-1300 MHz * Connectors: SO-239 * Impedance: 50 Ohm * Length: 15.75 inches * Max Power: HF 100W PEP, VHF: 60W FM, UHF 40W FM, 900 MHz–1.3 * GHz: 10W FM * SWR: Less than 1.3:1 below 500 MHz, Less than 1.5:1 above 500 MHz * Loss: DC-500 MHz = 0.5 dB, 500-900 MHz = 1.3 dB, 900-1300 MHz = 1.8 dB Whether you use one of these feed thru devices for a temporary coaxial installation or as a permanent no-hole solution, Comet Window Feed-Thru Jumpers from DX Engineering can get you on the air!

Comet CAA-500MARKII Antenna Analyzers

NEW and IMPROVED Comet CAA-500MarkII Antenna Analyzers retain the cross-needle analog function of their predecessor and add a full-color TFT LCD providing graphic and numerical, SWR, total impedance with R and X values (resistance and reactance), along with frequency and battery indicator. Comet was the first to offer a wide range SWR analyzer with an oscillator covering 1.8-500MHz. The new version also provides a very accurate, simple to use SWR and impedance analyzer to the Amateur Radio community. Their analog cross-needle meter displays SWR and impedance simultaneously as you sweep the chosen frequency range, instantly providing the information needed to make antenna adjustments. These Comet analyzers can scan your desired frequency range in seconds, allowing for quick SWR adjustments. Since SWR and impedance, resistance and reactance in ohms are all displayed simultaneously, you are able to determine resonant frequency more easily. These antenna analyzers, powered by six AA Alkaline cells, provide up to 10 hours of operation. With their built in trickle charger, you may also use Nickel-Metal Hydride (NiMH) cells. CAA-500MarkII analyzers have wonderful features: * Auto band sweep function: Switch to the amateur band of choice and press the "Sweep Center" button. The chosen band is swept and the SWR graphed in seconds. * Manual band sweep function: Choose the band, the center frequency, and the bandwidth and manually sweep the frequency range. * Multiple manual sweeps: The graph will overlay manual sweeps in 5 different colors! Make antenna length, position, height above ground, gamma match adjustments etc., and graph each adjustment in seconds without losing the previous graph! * SO-239 connector for 1.8-300 MHz range * Type-N connector for 300-500 MHz range * 8-16VDC external power or 6 AA Alkaline batteries (up to 10 hours of operation) or use Nickel-Metal Hydride (NiMH) cells * Built-in trickle charger (for NiMH batteries, only) * Battery indicator * External DC Power 2.5mm plug and cable included * Selectable auto-power off Note: For additional product information, please look at the files under the "Documentation" tab. The 500MarkII Analyzers retain the simplicity of analog measurements and add digital readout, sweep functions and a full color LCD screen to quickly, visually, analyze antenna performance and adjustments. Get your Comet CAA-500MarkII Antenna Analyzer on order from DX Engineering. Adjust and track YOUR antenna!

Comet CP-5NMO Mobile Antenna Adjustable Lip Mounts

Comet CP-5NMO Mobile Antenna Lip Mounts offer adjustability and over 16 ft. of deluxe cable assembly. These Comet mount and coax assemblies install in only minutes to your trunk lid, truck rear doors, SUV and van rear doors, hood lip, and more… without damage! Comet CP-5NMO mobile lip mounts feature adjustment in four planes. Their first 18 in. of coax is Mini RG-174 for easier entry through the vehicle's weather seal. The low-loss portion of the cable is fitted with NMO and PL-259 connectors, and the PL-259 disassembles completely for easier routing. A note about Comet coax: "The mini coax is neither RG-188 nor RG-174… it is actually 1.5D-QEFV Japanese coax. Comet states it is 'RG-174 type' coax because they have similar loss and diameter specifications. Initially RG-188 was used in comparison but was changed to the RG-174 comparison because they are more similar. The balance of the coax is Japanese 3.5D-QEFV. There is no 'RG' equivalent to 3.5D-QEFV. RG-58 connectors will not fit the 3.5D-QEFV coax, the Comet coax has a larger outside diameter and a larger central core and has about 30 percent less loss than RG-58. All of the coax cables produced by Comet use the Comet (Japanese) low loss coax. Mick Stwertnik - NCG Company" Max power for your Comet CP-5NMO mobile mounts is: * HF: 100 W * VHF: 75 W * UHF: 50 W These power ratings are due to the use of mini coax for maximum installation convenience.

Comet Triplexers

Are you in need of splitting off your HF, VHF, or UHF signals, then Comet triplexers are what you are looking for. Sometimes referred to as combiners or splitters, these triplexers are basically band-pass filters, simultaneously passing RF in both directions through the common connector, while the band-pass filters provide a high degree of isolation between ports. Additional information: * TX and RX from three radios at the same time into a single triband antenna. * Combine a triband radio with separate outputs into a single triband antenna. * Allow a single coax run into three antennas at the top of the tower, and three radios at the bottom, by using a triplexer at both ends of the coax run, avoiding cost and weight.

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!
