the power out on the SS amp in low position is 70 watts PEP using a true PEP reading wattmeter Autek One, not an Dosy. the TRC 458 ( wonderful radio best recieve ever on a cb bar none) Is only doing 18 watts pep, set up for audio quality not max power out.

Terrain search using lat and longitude shows the 5/8 wave 4 feet higher that the Sigma IV on terrain height.

No noticeable terrain structure between the test antennas and the mobile, It is NE Florida so not many terrain structures. ALL country with forest of pine trees between the test antennas and mobile.

I am not knocking the sigma IV, heck of an antenna, it may very well recieve better than the 5/8 wl, I don't know on that as I do not have one here to play with.
