Stay away from the low priced RG-6. I used to buy 500 foot rolls of RG-6 Quad from Home Depot to be used to feed my beverages and K9AY loop.   The cable was made in Canada. Its weakness is its PVC ja

I am absolutely convinced that tall trees next to a low band vertical have a very negative effect on my radiated signal. For the past 11 years, I have had the opportunity to live on 3 acres of land w

I have found that the quality, and therefore the loss, of RG-6 cable varies quite a bit. On the average, I measure about 14 ohms of resistance in 500 feet if shorted at the far end. Recently, I put u

Doug: I took shipment of my Hi-Z 4-8 Pro system in October. You can leave the delay lines coiled up just like they were shipped (Of course you have to separate the long and the short delay cables).
