Yes, but the inductances are all in parallel. I built a decent dummy load out of 24, 1200 Ohm, 10 watt wire wound resistors all in parallel between two squares of fiberglass PC board. The SWR was only about 1.2:1 on 15 Meters and about 1.5:1 on 10 meters. Admittedly, not a perfect load, but certainly adequate for the low bands just to soak up some RF.

If you're going to use the paralleled metal film resistor construction method, be sure to keep the resistor leads short and spaced them from each other. Lead inductance will start to become a factor on 6 m and up. I built mine with 40 2K 2W resistors and it works find at 100W if used intermittently. It's air cooled. Don't know how much putting it in oil would improve the dissipation.
