RE: RX Ant. Length
That is kinda where I was hoping to go with this. Continuous loaded ant's tend to have poor impedance matching so it is tough to get great performance. Keep in mind the GWS naro's have a 500' range real world it is less due to noise. but if we can compact the ant. and still keep the original reception strength Ya Hoo to us.

I have posted a calculator and freq chart so you can get an Idea what WL 1/2WL and 1/4WL's look like
