I'm sure you do, but for readers, if you choke right before your feed point, you absolutely need a counterpoise. If you are applying a choke to prevent the coax from being a counterpoise, than you need to give it something else to work with. A single 1/8w-ish wire will likely do as a minimum. Alternatively, if you have a long feed line, you can put the choke part way back, so the distant portion of your coax can still act as a counterpoise. 

Failure to give it any counterpoise at all will create additional balun losses as heat, and if pushed hard enough, saturating the choke and rendering it ineffective.
