The rule as written on page 53 of TNE FF&S Mk I Mod 0:

 

Radio, Radar, and EMS Jammers

   Radio, Radar, and EMS jammers have the same characteristics

as radios, radars, and active EMS, with three exceptions.
   1. Power use and cost are multiplied by 2.

   2. Antenna size for the radar jammer is divided by 10.

   3. Jammers may not be used as sensors or communicators, only

for jamming.

   Radio jammers may only be used to jam radios; radar jammers may be

used to jam radar and active EMS; and EMS jammers may be used to jam

radios, radar, and active EMS.

 

Area Jammers

   Area jammers degrade the effectiveness of sensor and communicators

that attempt to function in their area of effect. The principal design

decision, therefore, is the area of effect of the jammer, all other values

being derived from that. The area of effect is defined as the radius of

effect in kilometers. (Note that space-borne area jammers routinely have

an effective radius of 45,000 kilometers.)

 

Based on the above at TL-9 two jammers appear to be needed to jam both radar and radio.

From the reply at TL-9 or better to knock out radio, radar, and AEMS all you need is a radar

jammer, which means I’m out to lunch as usual.

 

At TL-10 both the EMS jammer and Area jammer are available, unfortunately I still am trying

to figure out which one is the better system.

 

The best minimum range for an EMS jammer is 480,000 km. If I am reading the Area jammer

requirements correctly an effective radius of 480,000 km for an Area Jammer the best feature

is the antenna area needed. By my calculations the EMS jammer needs an area of 2.6 m^2,

while the area jammer’s antenna is 0.9 m^2.

 

This may require errata for TNE FF&S and additional clarification in the T4 QSDS 1.5e sensor overview.
