Hi Paul, Its the perfect location for a Topband 4-square array! It would be even better if the array were in the marsh... Marshland Road, Hilton Head Island https://www.google.com/maps/place/32%C2%B0
Hi Ray, If you're back five wavelengths from salt water or salt marsh, almost the entire Fresnel zone will be over land and the salt water will make essentially no improvement . That's okay if the la

Don's email nicely describes the lack of salt water advantage when you're just 2500 feet from the ocean or salt marsh. Perhaps Don can describe the soil characteristics at his site 1/2 mile from the
Hi Mike, There's some vertical polarization off the ends of an inverted-V, but is significantly down from the horizontally polarized radiation broadside to the antenna. The advantages of a seaside lo
Hi Herb, Stew's two element inverted-V beam was 265 feet above sea level, a spectacular location. The water tower is on the edge of a steep drop to the ocean. 73 Frank W3LPL -- Original Message -- Di
This is a photo of the famous W1BB water tower in Winthrop, MA. http://www.sylviaplath.info/photos/winthrop9.jpg I've seen it many times flying into Boston Logan Airport. The photo was apparently tak

Hi Pete, Most entities needed to finish your first 100 entities for DXCC are northeast of you. Your best receiving antenna should be in that direction. The remaining directions in order of importance
Hi Jorge, Bill is almost correct, in most soils mechanical durability is the only consideration for long term durability of copper wire, but out of sight out of mind can be a big problem for radial s
Hi Jeff, Here's how we handle receive antenna switching at W3LPL: Six monoband receiving arrays are located 1000 feet southeast of the transmit antennas. Each monoband receive array feeds a W3LPL ban
As an alternative, in my opinion the receiving antenna switching capabilities of the K9AY 8x2 switch are far superior to any available alternative: - eight antenna input ports - two independently con
After hundreds of years of scientific research of sunspot cycles, no long range solar cycle forecasting model has ever been able to reliably forecast the intensity of a solar cycle until after the cy
Hi Bruce, Many of the two wire Beverage antennas used by RCA, AT&T and other companies in the 1920s were much more sophisticated than the simple two wire Beverage used by many Topbanders. While we ty
Hi Carl, I've never used an MFJ-1025/1026 so I can't comment based on direct experience. Perhaps someone else can comment. The DX Engineering NCC-1 is exceptionally well engineered for ease of use, i
Hi Rodger, You will have better success if you add a top loading wire to your mast, which makes it into an inverted-L. Suggest you start with an 80 foot wire in a straight line if possible but otherw
Until mid-2014 Solar Cycle 24 was remarkably quiet. Despite the steadily declining solar flux since mid-2014, the Suns large-scale magnetic field suddenly strengthened late in 2014 reaching its highe

Hi Jorge, one degree of phase on 160 meters is 18 inches. Any dimension less than 18 inches will have no significant affect on 160 meters. Your ground platew will work perfectly at 5 inches high 73 F
