Abstract: We study the tensor perturbations in a class of non-local, purelygravitational models which naturally end inflation in a distinctive phase ofoscillations with slight and short violations of the weak energy condition. Wefind the usual generic form for the tensor power spectrum. The presence of theoscillatory phase leads to an enhancement of gravitational waves withfrequencies somewhat less than 10^{10} Hz.
