As we mentioned in our last post about the DX Engineering Window Feed-Through Panel, the team at DXE has been hard at work developing new products to improve your amateur radio experience. Here are two more:
DX Engineering 1,500W Dry Dummy Load
The DX Engineering DXE-DL1500U dummy load features a lightweight slotted black aluminum chassis, which provides secure and efficient mounting, RF shielding, and air cooling for the large internal resistor. With a load resistor nearly three times larger than the resistor in a similar popular dummy load, the DL1500U delivers reliable performance and will provide years of dependable service.
The DL1500U should be used instead of an antenna as a stable 50-ohm, non-inductive load to a transceiver, transmitter, or RF amplifier on HF and 50 MHz:
- Whenever tuning or testing RF equipment for power output or signal quality
- To prevent interference with other stations
- To make audio adjustments on a transceiver while listening on a separate receiver
- To find initial settings on each band segment for variable components on antenna tuners
The dummy load operates from 0-54 MHz with SWR of 1.1:1 below 30 MHz and <1.25:1 SWR at 50 MHz. It handles 1,500W for 10 seconds of key-down CW and 100W for 10 minutes. The lightweight aluminum chassis provides air cooling and measures 4″ W x 3-5/16″ H x 11-5/8″ D, not including the SO-239 (UHF Female) RF connector.
DX Engineering LPFC-BNC Low Power Feedline Choke
This feedline choke is intended to be placed inline with coaxial-cable-fed antennas and equipment used for portable operations, including POTA and SOTA activations.
The DXE-LPFC-BNC coax wound toroid achieves an amazing common mode impedance (CMI) curve, with an RF choking capability that far exceeds “a-few-beads-on-coax” products offered by other suppliers. Actually, these “low power” chokes can be used in any station that runs less than 250 watts SSB.
Features and benefits include:
- Unique, lightweight form, with clear heat shrink over the choke*
- Light enough to hang inline at the feedpoint of any portable HF antenna
- BNC female connectors for easy connection to portable antennas and gear
- Much higher CMI than other portable, low power chokes, especially across the 40 through 6 meter bands
- Frequency range of 1.8 through 54 MHz
- RF power handling up to 250W PEP SSB, 100W CW and Digital (at SWR <2:1).
- Recommended for standard use to isolate either end of a coaxial cable
* Not intended for permanent outdoor use unless mounted inside a weatherproof enclosure.
This choke is ideal for use at any HF transceiver or receiver antenna connection, portable, mobile or base. In most cases, the DXE-LPFC-BNC prevents RFI, stops stray RF and noise on the feedline from getting into the receiver that would cover up weak signals, and improves efficiency of the antenna system. For any station, including POTA and SOTA, mobile and base, DX Engineering Low Power Feedline Chokes keep the RF controlled. In addition, the low power choke is included in the new DX Engineering Low Power Dipole and Winder Kits, which provide the parts to make your own single- or dual-band linked dipole.
