Inverted-L for 80m & 160m
The 18m glassfibre pole from spiderbeam is used, but without the top section too fragile to support the weight wind load of the 80m trap coil. The antenna itself is composed of 12m of heavy flexible insulated copper wire 4mm section + 7m of same but 2,5 mm on the top

Morgain 160mt
Shortwavers often have difficulty installing full-sized antennas for operation on low-frequency KB bands. One of the possible variants of the shortened about two times dipole range of 160 m is shown in the figure
Panoramica sulle antenne per la ricezione in 160 metri
Sulle bande basse, ed in particolare in 160 metri, e' importante poter disporre di un'antenna in ricezione separata da quella usata in trasmissione
Reduced-Size Half Sloper For 160 Meters,
Have you ever thought of trying 160 meters? Wintertime is the perfect time for exploring the Top Band. The atmosphere is relatively quiet, so you can mine 160 meters for all it's worth-lots of stateside contacts and plenty of DX
160 Meter sloper
This antenna ships 70' in length and will be trimmed back to 68' or less on installation. It works best when attached to your tower/pole at about the 45-50' level. This allows the radiator wire to be angled down
Working 160M From a Small Lot
A straight quarter-wave Best 1/4 - 125 ft at 1830 kHz with THHN Inverted L Good Go straight up as high as you can with a wire, then bend the remaining wire to run horizontal to resonate it Tee vertical A bit better than L - Like an inverted L, but the top is extended in opposite directions

Antenna switch arduino for icom IC-7300 A solution built around an arduino nano and one of the readily available four relay switching boards
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
