I use for portable 23 cm operation a small 15 elements yagi, home - made, after DL6WU design software. The construction it's very simple. It was made from copper heat system pipe, 1,5 m long boom and 15 mm diameter; copper 2.5 mm diameter (electrical cables) for elements. Soldered togheter. The adaptation was made from copper-teflon semirig coax. DL6WU design software will explain you all operations.
I do not like big (long) antenna for por portable operation.
My ideea it's not to have small angle in contests. You can easy stack 2 or 4 antenna for better results.
For small antenna also very easy to find a place in the car.
The best results I had with 80 cm, dish antenna (prime focus type) and home made circular feed horn.
Have 23 cm DB6NT transverter 20W out.
