PMM 9030 Frequency Extension 

10-15 

 

 

10.10.15 Using an  
               Antenna 

In the frequency range from 30 MHz to 3 GHz two different antennas, a 
Biconic and a Log-Periodic can be used to pick-up and measure RF radiated 
emissions; alternatively, some Biconi-Log antennas are also available to 
cover the whole range without changing between two antennas, even if such 
a solution is mostly more expensive and the antenna size is usually bigger.   
 
The really “unique” feature of PMM 9030 is that of allowing direct connection 
between antenna output connector and EMI receiver input, so dramatically 
increasing system immunity to environmental noise at detection side and 
completely cutting-off any capacitive coupling between antenna, ground 
plane and connectin cables. 
 
In order to perfectly match antennas to PMM 9030, a dedicated Teflon 
Antenna Holder is also provided as a standard accessory, so balancing 
weight between receiver and antenna when attached to a tripod or antenna 
mast. 
Such Antenna Holder comes with some spare parts plus nuts and bolts, 
which can be easily assembled with provided wrench, as per step-by-step 
operations in following pictures.
