Free for shipping from 66212, L101-A Attenuator. This is a piston/trumpet style attenuator. Good condition, has PL-258 female UHF connectors. I suspect that due to the piston design it is for use above 100 MHz. Pictures at: http://pix.sfly.com/V1oo_Fvj First come,first served, send zip code. Jack Holzer, W0YZS
