What it is and what it does
The Siemens 6GT2706-0BA00 is a SIMATIC RTLS omnidirectional antenna for 2450 MHz, delivering 5 dBi linear-polarized gain through an N-Connect male plug. It is the spare part for the RTLS4420G/A system.
RF and environmental fit
Rated for 50 Ω impedance with a maximum VSWR of 1.5, so the match is tight across the band — expect minimal reflected power back into the radio front-end. The plastic outer shell and -30 to +60 °C operating range cover indoor logistics environments and most sheltered outdoor deployments, but it's not IECEx rated for explosive atmospheres. Mounting is via the N-Connect plug itself — the evidence calls out the 6GK5798-2PP00-2AA6 cabinet bushing as a typical attachment point, so plan for a panel-mount N-type bulkhead rather than a mast bracket.
