About This Device
Panorama's LGMM series packs cellular MIMO, GNSS, and Wi-Fi elements into a low-profile roof-mount housing, and like any bolt-through antenna it is installed with sealing and fixing components designed for one compression cycle. Remove the antenna — to transfer it to a new vehicle, repaint or repair the roof, or correct its position — and those original components have already conformed and compressed to the first install. Reusing them is the most common cause of leaks and loosening after a remount.
The KRV400 is Panorama's answer: a model-specific reinstall kit containing the fresh installation hardware for the LGMM series. With it, a removed LGMM antenna goes back on a roof under the same conditions as a new unit — clean sealing surfaces, correct fixing hardware, and full clamping integrity around the cable penetration.
For fleet operators this small kit has outsized value. LGMM antennas frequently outlive the vehicles they are mounted on, and transferring a functioning antenna to a replacement vehicle costs a fraction of buying new — provided the remount is done with proper hardware rather than improvised parts. At roughly 0.05 lb, the kit is trivial to stock alongside spares; many fleet service operations simply add one KRV400 to every planned antenna removal work order. Panorama also offers matching kits for its other housing families, including the KRV401 for GPSD/SHKG series and KRV406 for Great White series antennas.
