4-Square Vertical Array

This high performance 4-square array controller uses the new Lahlum method of phasing and power distribution. This system is the most accurate method of obtaining the gain and deep backward pattern nulls. This method uses discreet LC networks just as any broadcast array would use, to accomplish the delays and magnitude. You can read all about it in the upcoming release of ON4UN's "Low Band DXing" book in May 2005 published by the ARRL. Until then please review in our manuals section.

Features

	Accurate phasing and power splitting contributes to higher gain and F/B
	Optimized phasing option for increased gain and F/B over quadrature feed systems
	50 ohm adjustable L network match to feed line for a perfect VSWR
	No lost dump load power since it does not use a hybrid coupler
	High power reliable relays proven in all our products
	High current temperature stable RF rated capacitors placed in parallel to have conservative currents in them, not cheap ceramics forced into RF duty
	Large inductors with optimum dimensions for high Q & low loss performance
	4 directions plus Omni-directional function to work the close in guys
	High quality WX proof enclosures for long life and reliability
