greetings to this community. This is my first post. I follow this forum for quite a long time.
I want to share my latest project with you.
It was my desire for quite a long time to create such a yagi and use it with my 6m pole.
I’d like to hear your opinions on it and may what could be improved?
Interesting project. I personally prefer the LogPer concept. Very robust construction without impedance adjustment, works on 2m and 70cm and fits into any backpack after unscrewing the elements.
At the moment I am using a commercial version with 4 elements and 7.1dbi on 144MHz und 8.7dbi on 435MHz
I am also interested in building a larger variety with over 10dbi/13dbi http://www.dl6ka.de/log.htm
I’ve always said you’re giving away the dB’s, Chris. Instead of making a wideband monster covering frequencies you don’t use, how about a small and lightweight 4 ele DK7ZB? The 50 Ohms version has > 7 dBd in free space on 144 MHz and works well on 70 cm at high gain. However, the radiaton pattern is a bit deformed then with the main lobes about 20° off.
Maybe Aleksander’s model works on 70 cm, too?
The LogPer looks really good. I would do such design too if I could find the materials here. Yes there is a choke in it. The design is from DK7ZB. Its a 50 ohm version.
