Purchase MFJ, Cushcraft, Hy-Gain & Ameritron Products While They Last
***
As we mentioned in our previous post about Cushcraft antennas, select MFJ products—including branded MFJ, Cushcraft, Hy-Gain, and Ameritron items—are still available at DXEngineering.com. MFJ, a fixture in the ham radio community for decades, ceased production of its lineup of equipment in May 2024.
Today we’ll be featuring just a few of the many popular MFJ, Hy-Gain, and Ameritron products that are in stock at DX Engineering. Please check DXEngineering.com for availability. As of this posting, the website includes the following:
Hy-Gain
MSHD Lower Mast Support Kit: The Hy-Gain MSHD Lower Mast Support Kit is designed to fit the HAM-IV, HAM-V, and T2X Tailtwister Hy-Gain rotator units. It’s manufactured from heavy-duty aluminum castings and is required for mounting these rotator units to a mast instead of to a flat mount surface. Stainless steel hardware is included. “This is one heavy-duty mount,” per one customer review. “Should give many years of service with no problems. Worth the money in a lot of ways!”
SPT-500 Super Penetrator HF Vertical Antenna: This 5/8 wave, 12/10 meter 1,500W power-rated antenna’s full-size radiator (with lower radiation angle) concentrates power closer to the horizon. Measuring 22.8 feet, it features large diameter, heavy-wall tubular construction. Four full-length radials and special machine-formed brackets give extra talk power and overall strength. Double-matching also provides a DC path to ground to drain off precipitation static, resulting in an extremely low-noise antenna capable of high power.
MFJ
849 HF/VHF Digital SWR Wattmeter
Featuring a large 3.5-inch bright orange LCD display, this meter reads SWR, and forward and reflected power digitally in a single glance. Handling 200W, it covers 1.5-525 MHz and features two sensors with SO-239s. An HF/VHF switch selects frequency range. The LCD is backlit, and the meter runs on 13.8 Vdc. The meter has a black-painted metal housing with rubber feet.
G5RV Multiband Antenna
This 102-foot center-fed dipole is capable of 1,500W and covers 160-10 meters with a wide range antenna tuner. It’s designed to be used as an inverted vee or sloper to be more compact. It may be used on 160 meters as Marconis (with a tuner) and a ground. The antenna handles full legal limit power. Just add a coax feedline and get on the air. Read much more about G5RV antennas in this OnAllBands article.
Five Stars: “Does a great job on all HF bands. No assembly required. Open the package, put it up in the air. I have been impressed with the reception and transmission on the HF bands (with an antenna tuner).”

1702C Antenna Switch
This switch employs center-ground protection. The unused terminal is automatically grounded for static and RF protection. It provides better than 60 dB isolation at 300 MHz and better than 50 dB at 450 MHz. Users can expect less than 0.2 dB insertion loss and nominal SWR below 1.2:1. The switch features cavity-type construction, 50-ohm impedance, mounting holes, SO-239 connectors, and the ability to handle up to 2.5 kW PEP.
1919EX Heavy-Duty Antenna Tripod
Supporting up to 100 pounds, the 1919EX tripod includes a built-in steel mast and a collapsible 15-foot fiberglass mast. Its steel mast is 1.6 inches in diameter and extends to a height of about 4.8 feet. The steel mast easily accepts most U-bolt antenna applications. Weighing only 9.75 pounds, the tripod collapses to 54 inches long by six inches in diameter. Its companion telescoping fiberglass mast employs MFJ’s QuickClamps for easy and secure height adjustments.
This 600W PEP (500W CW) solid-state linear amplifier uses state-of-the-art, high-voltage RF TMOS-FET devices in the power output section. The ALS-600 provides continuous frequency coverage from 1.5 through 22 MHz (160 through 15 meters**) with no tuning adjustments. Broadband five-pole low-pass filters provide output harmonic suppression in excess of all FCC requirements. Users enjoy instant band switching, no tuning, no warm-up, quiet low-speed fan, and SWR protection.
**10M and 12M operation with optional modification kit, FCC amateur license required.
Replacement Power Tubes
Choose from Ameritron 811A and 3-500Z tubes in stock:
75 Amp Switching Power Supply
Ideal for Ameritron’s ALS-500M 500W solid-state amplifier, this switching power supply provides 75 amps of output current continuously. The switching power supply has less than 100 mV peak-to-peak of ripple under 75 amps under full load, and load regulation is better than 1.5 percent under full load.
