COMPACtenna 2M/440+ Optimized High Performance Dual-Band Ham Radio Antenna
COMPACtenna 2M/440+ provides high performance using a unique Electric-Magnetic Field Diversity design, Patent No. 9,407,001. Superior Omni-directional coverage is achieved far beyond what would be expected for the antenna size. The multi-faceted geometric design of the antenna includes "extended flat monofilar spiral Tesla-like coils" that serve as the LCR matching system, resonating as an integral part of the signal field generation. No external or internal electronic lossy matching components are used. This design establishes diverse electromagnetic fields resulting in signal stability and performance greater than expected in NLOS (Non-Line-Of-Sight) environments, reducing the effects of ionospheric polarization shifts. COMPACtenna 2M/440+ Specifications: * Frequency Coverage: 144-148 MHz, 430-450 MHz * Power Rating: 100 W 2M; 75 W 70cm * Duty Cycle, Max. Power: 1 minute transmit limit in a 2-minute period * Repeater Operation: 30W maximum at the antenna * Maximum Ambient Temperature: 130 degrees F (hotter conditions, sun exposure, limited air flow reduces duty cycle) * Gain: +5 dB-MEG: Due to diverse EM fields of the Magnetic Field Resonator, performance is greater than predicted by singular polarization field-range tests * SWR, nominal: < 2.1:1 144-148 MHz, 430-450 MHz. Best SWR on VHF frequencies when COMPACtenna 2M/440+ antenna is mounted on an upper corner of a vehicle, NOT center mount. Flat style magnetic mounts provide the best SWR results. SWR varies with size and shape of the vehicle.

LDG Electronics AT-200ProII Automatic Antenna Tuners
There was a time when 100 watts was a lot of power. Today, more and more transceivers feature 200 watts of output. Even though many of these modern radios feature a built-in tuner, the tuners' range and features are usually quite limited. Break through those barriers with LDG Electronics AT-200ProII Automatic Antenna Tuners! They're designed for this new generation of rigs and are specifically recommended for Ten-Tec and tube radios. Many QRP operators have a small 100-150 watt amplifier for times when you need a few more S-units. The AT-200ProII tuners are ideal for this kind of operation; their minimum required power is only 5 watts, but they will handle higher power as well. The AT-200ProII tuners will handle up to 250 watts SSB or CW (75 watts RTTY, FT8) on 1.8-30 MHz, and 100 watts on 54 MHz. They feature LDG's state-of-the-art, processor-controlled Switched-L tuner. The AT-200ProII tuners will match virtually any kind of coax-fed antenna, including Yagis, dipoles, inverted Vs, slopers, loops, or just about anything. They will typically match a 10:1 SWR down to 1.5:1 in just a few seconds. You can also use the AT-200ProIIs with end-fed antennas, random wires, and antennas fed with ladder line with the optional LDG balun. Operation couldn't be simpler--while transmitting a carrier, just press the tune button. An automatic tuning cycle will begin and then end a few seconds later with the tuners set at the lowest SWR (almost instant for frequencies stored in memory). The AT-200ProII automatic memory tuners are the latest in a long line of innovative LDG Electronics tuners and will allow you to get the most out of your Kenwood, Yaesu, Ten-Tec, or ICOM radio that operates at higher power. Additional features include: * 5 to 250 watts SSB and CW (100 watts on 6M, 75 watts HF Digital, RTTY, PSK, FT8) * Easy-to-read LED bar graph display for RF power, SWR, and status * LEDs for antenna position and bypass * 4,000 memories (2,000 for each antenna) for instantaneous band changing * 2-position antenna switch with memories for four antennas on each position * Tuning time: 0.5 to 6 seconds full tune, less than 0.1 second memory tune * Built-in frequency counter for memory operation * Tunes 6 to 800 ohm loads (16 to 150 ohms on 6m), 6 to 3,600 ohms with optional 4:1 balun * Includes 6 ft. DC power cable * Power requirements: 11 to 16V DC at 750 mA max during tuning * Weighs 2 lbs. Note: For additional information, please look at the files under the "Documentation" tab. If you are running an older, high-output tube rig, a newer 200 watt rig, or have a small amplifier to give your QRP rig a boost, consider LDG Electronics AT-200ProII Automatic Antenna Tuners from DX Engineering!

Comet HD-5NMO Mobile Antenna Adjustable Lip Mounts
Comet HD-5NMO Mobile Antenna Adjustable Lip Mounts create the perfect pairing for your antenna support. Combining their RS-840NMO bracket and CK-3NMO5 deluxe coax cable assembly, these Comet HD-5NMO lip mounts offer a quality appearance with low-loss coax balance and easy installation. The mounts adjust in three planes, have a soft rubber pad to protect your vehicle's paint, and are held firmly in place with four large set screws. The first 18 in. of coax is mini-type for a better fit through the weather seal, and the coax cable is fitted with 24k gold-plated SO-239 and PL-239 connectors. 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" Due to the use of mini coax, power specs for Comet HD-5NMO mobile lip mounts are: * HF: 100 W * VHF: 75 W FM * UHF: 50 W FM For durability, quality low-loss coax and installation convenience, Comet HD-5NMO Mobile Antenna Adjustable Lip Mounts from DX Engineering offer great value!
