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.

MO-1 – 54 in. mast with fold-over at sedan roof line 15 in. above the base for hood, fender or trunk mount, natural finish MO-2 – 54 in. mast with fold-over at 27 in. above the base for bumper and hitch level mount, natural finish MO-3 – 54 in. mast with no fold-over, white vinyl covered, ideal for marine applications MO-4 – 22 in. short mast for truck top, white vinyl covered, including three longer stainless steel whips to allow each Hustler resonator used to properly tune. Hustler MO series masts are resonant on 50 MHz. Foldable models MO-1 and MO-2 have a shake-proof clutch sleeve. Add a resonator to make a "monoband" HF plus 6 meter antenna. Add a VP-1 Mobile Mast Multi-Band Adapter to create a mobile antenna with three HF bands… plus 6 meter! The choice of bands is yours and you can change bands by just changing resonators whenever you want, made especially easy with the QD-2 Quick Disconnect. NOTE: A Hustler SSM-2 Ball Mount or other heavy-duty 3/8-24 antenna mount is required. Add a RSS-2 Resonator Spring to protect it against low branches. These Hustler masts, resonators and accessories have been available since the 1960s. They were so well designed that they are still a great choice for HF mobile. Order Hustler HF Mobile Antenna Masts from DX Engineering and build the high-performance HF mobile antenna of your dreams!

COMPACtenna CompacCounterpoise NMO Mount Base Station Ground Plane
COMPACtenna CompacCounterpoise is a unique NMO Mount Ground Plane Radial Kit that turns the amazing mobile COMPACtenna models into sturdy, and stealthy, base station antennas. With four - 45 degree angled radials, optimized signal and SWR for VHF and UHF is now available for base station use of these COMPACtenna models: CAN-2M-440 CAN-2M-440PLUS CAN-2M-220-440 CAN-220MAX CAN-SCAN-III CAN-LMR-I With the CompacCounterpoise, these models are excellent for Base Station and Repeater use, particularly for low height above average terrain (HAAT) installations, where Non-Line of Sight (NLOS) propagation is substantial. Broad elevation coordinate signal pattern and elliptical polarization of COMPACtenna provide stabilized signals in our common Non-Line of Sight environments, with temperature and humidity inversion pathways, as well as tropospheric propagation and satellite communications. The CompacCounterpoise works well as an NMO mobile antenna base station mount for many other monoband or multi-band NMO mount antennas in the 144 to 512 MHz (144-1000 MHz COUNTERPOISE-N model) transceive range and above 512 MHz for scanner-monitoring uses. When not using a COMPACtenna model, results are dependent upon the NMO mount mobile antenna used (antenna not supplied with CompacCounterpoise). The CompacCounterpoise includes the 3 in. diameter mounting plate with mast bracket, clamps, four 18 in. radials and stainless steel hardware. This assembly includes the top flush mount NMO with gasket, a bottom SO-239 for PL-259 coaxial cable attachment on the CAN-COUNTERPOISE model and an N Female connector on the CAN-COUNTERPOISE-N model (coax cable not supplied). The mount's maximum power rating is 200 W up to 225 MHZ and 100 W on higher frequencies.
