2023年3月22日 · A couple of years ago, I put up the 80 meter skyloop antenna (better known as a sky wire antenna) in the yard. Since then, no other antenna has worked so well for HF, than …

A Broadband 80/160 Meter Dipole An easy to build single wire antenna for 160 and 80 meters with a better than 2 to 1 swr across the 80 meter band. by Gene Preston, K5GP I read Rick …

Figure 1 shows the basic doublet antenna design using 450 ohm ladder line to a remote 4:1 Current Balun; a short coax jumper to go into the house (shack); then connecting to an …

ening. This antenna covers 65 kHz of 160 meters, 75 kHz of 80 meters and the entire 40-meter band with SWRs under 2:1. The bandwidth limitations on 160 and 80 meters can be largely …

2020年12月23日 · One of the first articles about this antenna was from 1993, published in an ARRL article entitled “A Simple Broadband Dipole for 80 Meters.” The antenna uses a …

A practical 80 meter horizontal dipole is, however, not an ideal antenna for DX. For optimum communications with distant stations the antenna’s radiation pattern should have a null …

This antenna covers the whole range at less than 1.5 : 1 SWR (depending on the height above ground). And the frequency coverage can be tuned somewhat to center it in the band. Like so …

2013年4月3日 · Sure enough, many approaches, both old and new, exist to help an 80 or 75m dipole present a decent SWR across the entire 80m band. Many excellent examples are …

All that free antenna fertilizer certainly did make it grow well! I ended up using 44 feet of 2 inch army tent poles picked up at a salvage yard for the price of scrap aluminum. This pole is 44' …

2023年3月31日 · The actual Field Day site was in a parking lot at the top of a steep slope that dropped down to the East about 15 m (50 ft) to a road, then continued dropping for another …

Our model of the 80-2m Vertically Polarised Delta Loop. Side-leg fed showing the nice low angles on 80m. Modelling the antenna further, we run plots on other bands with the same feed …
