EGGBEATER ANTENNA

[gerald123]

just a thaught, I have made a eggbeater for the 145 MHz and intend making one for 430 MHz band...my question is if I put the two antenas on a boom, one on each side could I use a splitter inbetween them and use one length of coax to radio or funcube dongle. thanks in advance..........

not sure how you mean splitter..
just for receive yes, but the antennas won't be tuned for the frequencies as much as you'll be miss matching them by changing the coax characteristics..


not sure if anyone has ever tried an du-plexer backwards, instead of two radios, VHF and UHF use one radio and two antennas..

why not just use a duplexer 2/70 type. They will work both ways.

I've got two diplexers back to back for two antennas and two radios either end of a single length of coax... Think the split is somewhere around 75 MHz if I remember rightly, so I have HF on one side and VHF / UHF on the other.

A duplexer is something normally used in a repeater to allow the tx and rx to use the same antenna simultaneously. The thing you are looking for is called a diplexer...

[pwmonkey]

Yes, technically correct but you try searching suppliers websites etc for "diplexer" rather than "duplexer"
