Anyone ever seen one of these?? I have had one for years and never used it and was wondering what it will handle as far as power input. Heres what it looks like Archer Antenna Matcher - eBay (item 320589081013 end time Sep-18-10 09:30:17 PDT)
I just found one of these from a box of stuff I bought at a yard sale. What band does it cover? I'll be doing QRP. I'm just concerned if it just for CB.Another little piece of 'good news' is that most tuners are rated using Pep, not Avg power. That means if you plan to use 100 watts, that tuner had better be rated for at least 200 watts (300 watts would be even better).
Depending on just how bad the mismatch is, the resulting voltages can be really 'large'. That means the components used in that tuner have to be large too. That typically means wider spacing between coil windings and the plates of the capacitor(s) used. The physical size of a tuner isn't a good way of telling what the thing is capable of, but it can certainly give you a 'broad' general idea. I have no idea how to make a "watts per cubic inch" guess about tuner sizes, but in general, bigger is better. If the mismatch isn't very much, then the tuner doesn't have to 'be' very much. If that mismatch is sort of large, then the tuner ought'a be huge. Bad way of putting it, but...
