Problem $2$:

An antenna, connected to a $150-$ lossless line, produces a standing wave ratio of $2\mathrm{.}6.$ If measurements indicate that voltage maxima are $120$ cm apart and that the last maximum is $30$ cm from the antenna, calculate

$($a$)$ The operating frequency

$($b$)$ The antenna impedance

$($c$)$ The reflection coefficient. Assume that $u=c.$

$($d$)Z_{in}$ and $Y_{in}$ at the generator if the line is $60$ cm length.

$($f$)Z_{in}$ and $Y_{in}$ at the generator if the line is $90$ cm length.
