On the website of DL5NEG I found an interesting 23 cm antenna; it is a bi quad antenna which can be homebrewed with the use of 1mm diameter cupperwire.
The antenna is discussed here:
The antenna should have a gain of 10 dBd, which is not that bad compared to difficult yagis.
Maybe it is worth a try to build it during a rainy weekend. A simple improvement can be made by using another type of 50 ohms coaxial cable. Instead of RG58 for example Aeroflex can be used. Little bit more expensive but less RF attenuation
