ALPHA DELTA DELTA-C Alpha Delta Antenna Hardware Kit
Alpha Delta Antenna Hardware Kit (Including center insulator with SO-239 connector, 2ea. Model CIN end insulators, Model SEP ARC-PLUG (tm) static protector)
ALPHA DELTA DX-LB-PLUS Dipole Antenna
Low Band Dipole Covers 160-80-40 meters with an overall length of only 100 ft. Plus Model adds parallel wires for operation on 20 thru 10 meters. Antenna performance and 2:1 VSWR bandwidth is site dependent and varies with height above ground and surrounding objects. The typical bandwidth is: 160M – 20kHz • 80M – 40 kHz • 40M – 300 kHz Full band coverage can be accomplished with an antenna tuner. Built with insulated 12 ga. wire, stainless steel hardware and uses the Model DELTA-C static protected center insulator and CIN end insulators. Use coax or open wire line and configure as a dipole or inverted-V. Assembled and ready to go!

ALPHA DELTA ATT3G50F 75 Ohm Coax Surge Protector with Female F Connectors
Transi-Trap Surge Protectors are gas surge arresters designed to protect sensitive electronic equipment from damage due to excess voltage or currents generated by transient phenomena (lighning or static buildup). Frequency: 0 - 3000 MHz Insertion Loss: Less than 0.1 dB from 0 to 1000 MHz Less than 0.2 dB from 1000 to 2000 MHz Less than 0.5 dB from 2000 to 3000 MHz VSWR: Less than 1.1: 1 from 0 to 1000 MHz Less than 1.3: 1 from 1000 to 1000 MHz Characteristic Impedance: 75 Ohms DC Blocking: None, Will pass DC for Power and Control purposes Max DC or peak AC is 150 V. Connectors: F Connectors Female Note: These devices are not intended to protect equipment, personnel or structures from the effects of a direct lightning strike as these events are unpredictable in strength and vary widely in severeity. Direct lightning strikes can cause building damage, including damage to AC connected appliances and equipment induced through AC power lines.
ALPHA DELTA DELTA-2B-TNC 2-Position Coax Switch with TNC Connectors
Alpha Delta DELTA Series Surge Protected 50 Ohm 2 Position Coax Switch with TNC ConnectorsPower Rating: 1500W PEP/CWImpedance: 50 OHMSConnectors: TNCLightning Surge Protection: Alpha Delta Model D-4 internally mounted, field-replaceable ceramic gas tube Arc-Plug Cartridge PillSpecial Switching Functions: When the knob points to the center(ground) switch position, all antenna circuits are internally disconnected and grounded. When the knob is in the active position, the unused antenna ports re grounded. Then active position circuit is continuously protected by the Model D-4 Arc-Plug Cartridge Pill.Grounding Requirements: A separate, external ground wire must be used from one set of user supplied mounting hardware (through either thru-hole on the base plate) to the station ground system. (Not the equipment chassis.) The Arc-Plug Cartridge Pill will not operate without a good ground. Note: Paint should be removed at point of ground hardware connection to base plate. It is also good practice to ground hardware connection to the base plate. it is also good practice to ground the coax shield at point of entry to the building.

ALPHA DELTA DX-40 40M Mono-band Full Size Dipole Antenna, Rated up to 2000 Watts
DX-40-- 7.0 -30 MHz (Length 67’) The system consists of an assembled dipole antenna which is pre-tuned for the lowest indicated frequency and 40 ft. of mounting rope. The antenna is constructed using Alpha Delta's exclusive Model Delta-C center insulator and Model CIN end insulators which are molded of Deltalloy™, an extremely tough and durable plastic specifically blended to withdstand sunlight and extreme weather conditions. The use of stainless steel hardware and heavy 12 gauge PVC coated solid copper wire assures that the DX-Dipoles will tolerate the harshest environments. Also, the Delta-C center insulator contains the Model SEP static electricity protector which continuously discharges potentially hazardous static charges which can be produced by wind, rain, snow, sand and other natural phenomenon. The Model SEP cartridge is field replaceable, but should last for many years under typical conditions. The DX-Dipoles can be used as very effective multi-band antennas for all frequencies higher than the pre-tuned frequency when used in conjunction with an antenna matching unit (antenna tuner) with balanced output and fed with open-wire feeders or low loss feedline (not coax). The open wire feeders or ladder line is connected directly to the #10 stainless steel bolts on the Delta-C center insulator using the wingnuts and washers provided. Important: When operating the dipolesin a multi-band configuration, it will be necessary to remove the SEP Cartridge due to the high voltage present at the antenna feed point. Note: When using the DX-dipoles for receiving only, it is not necessary to remove the Model SEP Cartridge regardless of the frequency of operation. SEP Failure: The Model SEP cartridge should last many years under normal circumstances, but the cumulative effect of thousands of discharges or a very strong surge can destroy the device. The SEP is designed to “fail-safe” in a shorted condition and this will be apparent due to an increase in SWR during transmit and/or a severe reduction in received signal strength.
