If room is a restriction, here is something to consider

Minimal cost and works quite well on the bands advertised and I have worked
into Europe on three watts.  But again you have to consider the band
conditions.

Well, I bought a 20M and a 40M Isotron, just to try them out. 

Totally unscientific tests...all you EE PHds can cringe.

1. Mounted 20M Isotron on 20' Aluminum mast. Tuned it for 1:1 SWR no
problem. 
Compared to bumper mounted Hamstik on 1981 VW Rabbit.  Hamstic was at least
1 
S unit better every time.

2. Mounted 40M Isotron on leg of tower at 30' level. Tuned for 1:1 SWR, no 
problem. Stations that were S7 or less on my 35' high trap dipole were 
inaudible on the Isotron. I made 1 QSO with the dipole, 589 RST, switched to

Isotron and he could barely hear me.

Conclusion: Isotron makes an excellent dummy load.
