BA3QU SuoYuC Of course, it can't be that simple! If you just casually pull down an antenna and play around with it, wouldn't a HAM who builds large antennas be wasting their time? Haha.
BH2UOD SuoYuC It's unlikely you'll be able to lift 80 meters with a 750 kg load. I recommend using a 40-meter pull-back (without adding damping) for a better experience.
SuoYuC BI4UMB The main focus of this activity is participation, and I also want to test the lower limit of my system.
BH8ESR For low frequencies, I recommend using longer cables. Tonight's 160 MHz band seems to be quite active. B3, B5, B7, and B8 are all present.
SuoYuC BA3QU Thank you for fulfilling my small wish of 160 meters; I'm using a 20-meter antenna to transmit, with an SWR of 2.6 and a power output of 16 watts.😆
BH3XZT Replace the MN-100 antenna with an IC, ensuring that the SWR (standing wave ratio) across the entire shortwave band is no more than 1.5 (including non-amateur bands).
BD5XX The difficulty lies in the antenna. Using a traditional, manually adjusted antenna results in very low efficiency, and there is very little power remaining at the antenna's output end.
BG3LGO The focus was on participation; I only managed to transmit four segments, and couldn't transmit any others.
BG5LU The 7M full-sized inverted V antenna was difficult to use, even with a manual tuning system for the power amplifier. It had very low efficiency and ultimately, I gave up on using it in the 80m band.
Lynx Last winter, I built a 40-meter long inverted L antenna, using 160 meters of wire and 5 watts to transmit to Taiwan, and 1 watt to transmit to Vietnam.
