A dual band receiver owned by Geodetic Observatory. Constructed at TTI Norte, Santander, Spain. This receiver is used at Metsähovi for geodetic VLBI observations. The receiver operates at two different bands i.e. 8150-8650 MHz and 2210-2350 MHz. The receiver front end consists of cryogenic LNA's and a bulky feed system and polarizers at room temperature. This receiver needs a large subreflector (with diameter of 1.7 m) which is placed in the front of the original one, therefore simultaneous observations with mm-receivers are not possible.
