Looking for ONE 900MHz and ONE 1800MHz antenna with these specifications:
1/4 wavelength monopole
50Ω input impedance
VSWR<2

Please tell me the part number of it or suggest an equivalent one.
THANKS !

 

What power level? Do you want one antenna for each frequency, or two antennas.
Maxrad, Antenna Specialists, make these suitable for mobile installations e.g. 3/4" hole mount. Includes "X" amount of cable and connector of your choice. These two companies plus "Rubber Duckie" make flexible antennas for handheld radios. The power is limited to 3 watts or so, also with a variety of connectors. I used to use a suppliery named Tessco, they had all of this and much more.
