Good Dummy Load, Handles 25W Continuous No Problem. I received a CelWave 60W Dummy Load from ARS a couple of weeks ago, and it seems to handle the RF power from a radio that I have. I tried this at 5W, then 15W, then 25W and keyed the radio for 3 minutes straight at 25W without any major heating of the dummy load. I tried this for 2m and 70cm frequencies from the radio, with an inline power/SWR meter in the feedline cables. Confirmed 24.5W out of my radio at 146.000 MHz and no problems with thermal management.
SWR was very good, 1.00 in the 2m band, 1.02-1.03 in the 70cm band at 25W nominal TX. The N male connector seems to be well done, just make sure you hold both ends of your connection securely when joining or your connector inner conductor section may spin. Mechanically, this seems to be quite solid.
The one item that did catch me by surprise is that I was still able to send/receive repeater traffic through the dummy load to some nearby repeaters, especially to a nearby machine around 447 MHz. The return signal is normally strong anyway, but I was getting about S3-S5 on my power meter. Signal was weak but very clean as an antenna... Take that for what you will as a dummy load. I did not receive any RF burns or notice any significant interference in the room where power was applied to the dummy load.
Overall this seems to be a great unit, especially for the price. I do recommend.
