Narrative:
While taxiing aircraft X; a B737; from terminal X to company hangar. We established radio communication with ZZZ ground tower at spot xa. Tower's instructions were to give way to a different air carrier B737 aircraft follow taxiway to hold short runway 36R. After several takeoffs we heard our call sign X. I working radio VHF #2 responded; 'X go.' I believed the tower to have said cross runway 36R. My come back was cross runway 36R I'm having difficulty reading you; at that point we discovered my #2 radio was intermittent. Tower responds that's obvious hold short runway 36R at that point we were in the middle of runway 36R believing tower to have cleared us to hold short of runway 36L. While crossing runway 36R my #2 radio came back up working normal. While taxiing on a B737 do not ever use #2 VHF radio for communications; antenna is on the bottom; and could encounter dead spots. Radio communication unreadable with VHF #2 on ground.

Title: A B737-800 ON TAXI FROM THE TERMINAL TO THE HANGAR EXPERIENCED A RWY INCURSION DUE TO #2 VHF INTERMITTENT DURING GND CTL XMISSIONS.
Narrative: WHILE TAXIING ACFT X; A B737; FROM TERMINAL X TO COMPANY HANGAR. WE ESTABLISHED RADIO COM WITH ZZZ GND TWR AT SPOT XA. TWR'S INSTRUCTIONS WERE TO GIVE WAY TO A DIFFERENT ACR B737 ACFT FOLLOW TXWY TO HOLD SHORT RWY 36R. AFTER SEVERAL TKOFS WE HEARD OUR CALL SIGN X. I WORKING RADIO VHF #2 RESPONDED; 'X GO.' I BELIEVED THE TWR TO HAVE SAID CROSS RWY 36R. MY COME BACK WAS CROSS RWY 36R I'M HAVING DIFFICULTY READING YOU; AT THAT POINT WE DISCOVERED MY #2 RADIO WAS INTERMITTENT. TWR RESPONDS THAT'S OBVIOUS HOLD SHORT RWY 36R AT THAT POINT WE WERE IN THE MIDDLE OF RWY 36R BELIEVING TWR TO HAVE CLRED US TO HOLD SHORT OF RWY 36L. WHILE XING RWY 36R MY #2 RADIO CAME BACK UP WORKING NORMAL. WHILE TAXIING ON A B737 DO NOT EVER USE #2 VHF RADIO FOR COMS; ANTENNA IS ON THE BOTTOM; AND COULD ENCOUNTER DEAD SPOTS. RADIO COM UNREADABLE WITH VHF #2 ON GND.
