The antenna can be pole mounted at ground level or elevated depending on the user's personal requirements. The antenna is rated at 1KW pep. The antenna comes with fixings and installation guide. How it works: The antenna is fed using 50 Ohm coax via a SO-239 socket at the base of the unit a 4:1 UNUN transformer is located in an IP65 weather sealed box at the bottom of the bracket section of the fibre glass elements.
The antenna comes in four parts, three fibreglass poles and one stainless steel tapered whip. The transformer reduces the impedance at the feed point to a more acceptable level making the antenna much more efficient and allowing proper and easy tuning via an external ATU and automatic ATU's found in most modern radios.
The antenna can be grounded if the user experiences excessive local static noise, but as the UNUN is DC grounded: grounding will not affect the tuning ratios. 3.5 MHz 80m 1.1.5 MHz 60m 1.1. 7 MHz 40m 1.1. 10 MHz 30m 1.2.
Frequency TX / 3.5 - 52 MHz. 14 MHz 20m 1.1. RX / 1.8 - 55 MHz. 18 MHz 17m 1.1.
1 kW PEP or CW. 21 MHz 15m 1.1. & 200 watts max for data modes. 24 MHz 12m 1.1.
28 MHz 10m 1.1. 29 MHz 10m 1.1. Length 5.5 meters 18 feet. 50 MHz 6m 1.3. Please use a good quality 50 Ohm coax, rg-213 or Mini 8 are probably the best choice.If you are using a high-power amplifier it is essential that an external ATU is used between the antenna and the amplifier, otherwise damage may occur. Measurements were made using a Yaesu FTdx1200 and internal ATU and a Yaesu FT450D and external LDG-1200 ATU.
