MKII VHF/UHF Base Vertical Antennas
Constructed from durable, weatherproof fiberglass, these compact base station dual-band antennas are pre-tuned to operate efficiently across 144-146 MHz and 430-440 MHz. All models come with three rigid radials—6.7″ for the 2241/228 and 7.48″ for 2301. Mast mounting brackets and hardware included.
The 150W 2241 model gain numbers are 3 dBi (2M) and 6 dBi (70cm); the 200W 228 model has gains of 4.5 dBi (2M) and 7.5 dBi (70cm); and the 200W 2301 Super Gainer version has gains of 6.8 dBi (2M) and 9.2 dBi (70cm). All models have VSWRs of 1.5:1 or better. They are also suitable for portable use. Click on the links here for more details:

GAP-H Half-Wave Vertical Antenna (MKR-11-600)
Crafted from durable aluminum, Moonraker’s GAP-H vertical is designed to cover the 10M and most of the 11M CB band within the 26-30 MHz frequency range. Features of this 18-foot, no-ground-plane antenna include gain of 2.4 dBi, minimum VSWR of 1.5:1, 500W power handling, and easy mounting on a standard-sized mast with included U-bolts.
What do hams say about the Moonraker GAP-H Half-Wave Vertical?
“Five stars: The hardware is heavy duty and the telescoping action is easy to deploy. Good reception and fast shipping.”

Mobile Antenna Right-Angle Mirror Mount (MKR-15-065)
This aluminum mount features a UHF mount (SO-239) and 13.1 feet of RG-58 coaxial cable with a PL-259 termination. It fits up to one-inch mirror bars but can be extended with longer bolts.
Mobile Whip Dipole Center Mounts
These center mounts are designed to be used with two HF monoband mobile whips to create a single-band mini dipole. Available in either a straight or V-shaped dipole configuration, the 500W-rated center mounts feature two 3/8″-24 threaded inserts, so they’re compatible with a wide range of mobile whips. A UHF SO-239 female coaxial connector is provided for connecting your coaxial cable.
- MKR-09-159 : Dipole Center Mount for Mobile Whip, Straight
- MKR-09-161: Dipole Center Mount for Mobile Whip, V-Shaped
Also available are the Moonraker AMPRO Heavy-Duty Mobile Whip Center Mount (MKR-09-167), Heavy-Duty Pole Clamp Mount for Mobile Whip (MKR-09-190), and Wire Dipole Center Insulator (MKR-09-163, check website for availability).
MRW-HF100 HF Base Loading Coil & Antenna Pack
This all-in-one solution for multiband portable operations contains a set of 50W quarter-wave base loading coils covering 40/30/20/17/15/12/10/6M. Each coil is labeled to make it simple to find the band you need. The kit comes with a telescopic element that can be extended from 7″ to 53″ and easily screws onto your chosen coil. Coils are terminated with a BNC-P (plug) connector, making it simple to connect to most portable transceivers.
The provided manual provides suggested element lengths per band. Moonraker lists gain at 2.15 dBi and VSWR at less than 1.5. Just tuck this kit into your backpack and you’re ready to go portable!
Slider Multiband Manually Tunable Mobile Whip Antennas
For quick and effortless tuning, these wideband mobile whips can be manually adjusted by sliding the telescoping, PL-259-terminated coil at the base. This base coil sleeve easily slides up and down to make adjustments for resonance. When the resonant point is found, a twisting nut lock secures the sleeve in place to prevent detuning.
The top whip may also be adjusted for ultra-fine-tuning and optimizing VHF/UHF performance. With the MD-3500 model, a separate loading coil is included for 80M operation. Both models have maximum power handling of 130W SSB and 5o-ohm rating.
- MKR-12-122: MD-7400 HF Slider Antenna, 40M-70cm, 5.8 feet
- MKR-12-124: MD-3500 HF Slider Antenna, 80M-6M, 8.53 feet
SM-30II Switching Desktop Power Supply
The SM-30II features an adjustable output voltage range of 9-15VDC or 13.8VDC switched with a rear panel 13.8VDC setting, ensuring versatility for various applications. It includes a noise offset control system, which eliminates pulse noise from the DC output. This patent-pending function is designed for communication equipment use (effectiveness varies depending on frequency/mode).
The unit has dual analog meters for real-time monitoring of voltage and current. Other features include short-circuit protection and automatic current limiting over 30A; lightweight (5.51 lbs.), compact (6.7″ W x 4.7″ H x 9″ D) design; two-pair snap-in DC terminals; and screw-on terminals. Input voltage is 120VAC. It is also available in a 50A model (SM-50II).
