Directly observe the finished product, a true fishing rod antenna (dog head).


However, the balcony was too hot and had a lot of obstructions, so I moved it inside to a room with air conditioning. All I needed was something to prop it up.


Let's look at the metrics; they aren't infinite.

The effect would be like:

After buying a BOX6, I've used it on several occasions. The main time I use it is in the evenings after work. During the day, I generally don't use it. I mainly use it in Japan, the Philippines, and Indonesia, as well as occasionally in Mariana Islands and Taiwan. Otherwise, I rely on friends who live nearby to help me broadcast (this is how I achieve 6m).



Finally, let's discuss the pros and cons.
Advantages: It works. The cost is extremely low, requiring only a long wire for the oscillator + a 75 ohm matching line + a 50 ohm feedline to connect to the device. The stand can be used with fishing rods or other types of rods. The total material cost is less than 20 yuan. The performance is controllable and easily adjustable. If you also want to build one, you can watch BG7QKG's video on Bilibili.
Disadvantages: Ugly appearance. Poor water resistance. Furthermore, to avoid complaints, I always put it away after each use, which is inconvenient. Also, to make it easier to use next time, I don't wind the line completely; instead, I leave it on the fishing rod. This allows me to easily store and retrieve the rod by leaning it against the wall, but results in a messy tangle of line when stored (I have to fix this at night). Finally, its loose structure means that the readings fluctuate significantly each time it's set up. People with obsessive tendencies have to use a plumb bob to measure the readings and make several adjustments to the transducer before achieving perfect readings.
Conclusion: It's still necessary to pull the entire handle.
By the way, I welcome anyone who wants to exchange cards with me, and I support eyeball (
