Tim's idea is a fine one. Alternatively, you could use AA2TX's lindenblad designs. You can even get away with a simple groundplane bolted onto a female bulkhead N-connector. In all these cases, though, the most important addition to your setup, especially on 70cm, will be a low-noise preamp which is connected to the antenna by a short run of very low-loss coax, such as LMR400. Finally, as for hand-held use, have you tried operating your ht with hand-held yagi indoors as if you were out-of-doors? Depending on the sort of building you live in, this can work fairly well. 73, Bruce http://ve9qrp.blogspot.com _______________________________________________ Sent via amsat...@amsat.org.
