Are you referring to masts that come in 10' sections and can be
assembled together, one inside another? If this is what you are
wanting your Ace or True value hardware have them or can order them.
Mine cost me 2 weeks ago $15.99 each plus sales tax. They fit one
inside another to whatever height you want.


Also, if you have a Lowes Home Center nearby, they do tend to carry
those Wineguard type telescoping TV antenna masts, too. ... at least to
the 40' variety. Whether or not you'd find one in stock or have to order
is another story...
