The word is spreading about Palstar's unique, high-end amateur radio products. Carrying on in the Palstar tradition for products of the highest quality designed by Hams for Hams. The American made BT1500A tuner is no exception.
The BT1500A is a dual-roller balanced L antenna tuner that fills the void for a matching network up to 1500 watts pep for balanced line antennas. For ease of use the BT1500 utilizes only 2 controls to operate for tuning with two direct-
coupled precision ceramic roller inductors. As on all Palstar tuners the front panel and top cover are powdercoated.


So why buy a balanced tuner?
Joel Hallas described the problem many antenna tuners experience in his September 2004 QST article on balanced tuners (click here to read it). He wrote, "unfortunately, the typical random sized center-fed antenna with random length ladder
line feed has an impedance at the feed point that varies dramatically with frequency. The result can be heating and loss (and occasional damage) at the balun...the classic solution has been the use of an inherently balanced tuner."

In his QST article Joel Hallas reviewed the Palstar AT1500BAL as a high-power solution for amateur enthusiasts looking for a balanced tuner. The engineers at Palstar took the AT1500BAL and reengineered the entire tuner inside and out
reintroducing it as the BT1500A balanced antenna tuner. Peak and Peak Hold dual cross-needle metering ($149.95 value found in our popular PM2000A wattmeter).
