WiMo-Yagis use N-jacks (female), the balun is protected in the connector box!
The dipoles are true folded dipoles with a Teflon balun mounted in the center feed. This is a non-compromise solution avoiding the known problem of RF travelling along the outer surface of the coax's shield. Similar to the 2-m antennas the connector is an N-type. The center feed box is absolutely weather proof, sealed and additionally filled with Styrofoam. The Teflon balun is embedded into the center feed box. As seen with other antennas there are no balun slopes hanging out of the connection box and no need to affix the slope somehow to the antenna. Consequently, this design has no problems whatsoever with humidity leakages.
WiMo-Yagis use 8 mm diameter on elements (below)!
We utilize elements with a diameter of 8mm. This results in an extended bandwidth but same gain compared to thinner elements! The windload increases just a little bit which plays absolutely no role when using today's modern antenna rotors. Material of the elements: A highly conductive aluminum alloy we use to minimize the skin effect; DK7ZB has calculated (based on technical material from K6STI) that the losses due to the skin effect can add up to 0.8 dB for antenna elements made of stainless steel. Of course, the losses are even worse in the 70 cm band.
WiMo-Yagis use screw-on elements!
Fixed is fixed - we are not in favor of clamp-on connectors. The WIMO-Yagis feature elements which are fixed to the boom by means of stainless steel bolts and nuts. This guarantees low-resistance and un-hampered functionality for years to come. Each element is fixed to the boom by means of a 3 mm stainless steel bolt. We assure you we never "lost a boom" because of the additional screw holes in the boom!
WiMo-Yagis use stainless steel screws!
All nuts, bolts and washers are made of stainless steel with the exception of the mast clamp itself. This guarantees a long antenna life time. The antenna element mounts are made of Polyamide material which is highly resistant to the destructive effects of ultraviolet light. In case of the cross yagis the elements are fixed to the circular boom made of aluminum.
Crossed yagis without strut!
WiMo crossed yagis can be mounted diagonalyy or horizontally/vertically!
The antenna boom of the cross yagis is made of circular aluminum tubes (only exception is the 2 m 4-element antenna). The well designed and exceptionally manufactured mast clamp allows mounting of the antennas as well in a horizontal/vertical ('+'-Form) as in a diagonal ('X'-Form) shape. Because of the circular boom our cross yagis do not require an additional support strut; consequently the already perfect antenna diagram cannot be affected by the support strut...
Location of Mounting Clamp
WiMo-Yagis allow balanced mounting of the antenna!
All long yagis with twin boom (except WY-214) have a separate boom-connector for installation; such the mast clamp may be mounted independent from the boom-connection at the center of gravity (not on WY-214).
German and english instructions
WiMo-Yagis have an excellent manual and description!
The detailed English and German manuals contain also tips and tricks for stacking, combining etc.
