About moun�ng each element

If it is installed near the horizontally installed antenna

element and parallel to the wall, VSWR may not be

improved.

In that case, try changing the m

oun�n

posi�on of e

ach

band coil.

Example of mounting each element [View from above]

When opera�ng in 9 bands, the lateral

extension of the 7 MHz band element

becomes longer. Please be careful about

contact accidents.

Please note that some bands have diﬃculty in reducing

SWR due to mutual interference between the bands.

Note : Adjust the SWR of each band to the best possible

condi�on before using the antenna tuner.
