Why have anything less than the best performance? This is by far the best on eBay and the price is more than reasonable.

If you were to buy these parts and build your own you would be spending much more.. we buy in bulk and this is why we can do it at this price.

Warning never use any 9:1 ulun with wire lengths less than half wave length for the band of operation poor performance and extreme voltages generated 14,500v  @1 00w is not uncommon. On very short antenna lengths always use the formula  467 / frequency = half-wave antenna length in feet.
