WebGenerally speaking, if an antenna analyzer or (other) transmitter shows that the antenna output presents a SWR of 1:1, then what you have is probably about as good as it gets. That does not necessarily mean that what you have is a good antenna setup as exemplified by the extreme example of a dummy load. Web16 de jul. de 2024 · Now drop the wire vertically for a length of 360mm and secure again. Wind on 22 turns (in the same direction as previously) over a length of 70mm and secure again. Then wind three turns, wide spaced over 820mm (and secure again leaving the end free. This end then needs attaching to your 4:1 UNUN. For the 4:1 UNUN you can either …
WebNever stretch to reach a point– instead, move the ladder. Have the ladder on a secure footing, and have someone there to hold the ladder. 3. Make sure your antenna is in a safe place, high enough so people or pets won’t walk into it by accident. (Plus, the higher up you get it, the better it works). 4.
