The performance of candidate protocols for first-generation Ku-band very small aperture terminal (VSAT) satellite networks is compared. The goal is to assist the process of selecting a protocol. The performance comparison is carried out over a range of possible traffic, channel and satellite parameters, leading to an understanding of the appropriate regime for each of the protocols under consideration. The protocols considered are unslotted Aloha, slotted Aloha, selective-reject (SRE) Aloha, and demand-assigned time-division multiple-access (TDMA) or DAMA.< >

The dip-meter for detecting resonance in L-C circuits and transmission lines has all but disappeared. For those who occasionally have need to explore resonant conditions, the author has found a suitable substitute in a wideband signal generator and a sensitive RF millivoltmeter. Measurements have been made from low radio frequencies to over 2 GHz.
