Capacitance vs Inductance
Capacitance vs Inductance
(OP)
Hi Everyone - Trying to figure out which is worse, too much capacitance on a line or too much inductance? Any perspective you may have on this would be appreciated.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Capacitance vs Inductance
For example in using an "antenna tuner" to match a transmitter to a multi-band antenna impedance at a given frequency, I like to size the antennas slightly larger, so that it has a bit too much inductance on the planned operational frequencies where there will be some mismatch, because using air capacitors to add capacitance to balance out the excessive inductance is quite efficient.
On the other hand, the IR loss encountered in a variable inductor coil to add series inductance to balance out excessive capacitive tends to be quite lossy.
Therefore, I consider have too much capacitance (antenna impedance) in this situation "bad".
Your mileage in your application may vary...
