The Napier Amateur Radio Club “Q” VHF/UHF Antenna Project

The Completed “Q” Antenna ready for use. It does look like a Pool Q!

This antenna was recently developed by Laurie, ZL2TC as a Club project for the Napier Amateur Radio Club. The design brief was for a simple, rugged 2 M/ 70 Cm antenna that is easily constructed by club members in an evening. We ended up with a repeatable design that acts as an end-fed half-wave dipole on 2 M and a 3 dB gain collinear antenna on 70 Cm. The SWR is unity on 2M and less than 2:1 on 70cm and is very effective in triggering local repeaters. The stiff 2M long tapered fibreglass housing is UV resistant, waterproof and the base of the antenna is a 28mm alloy tubing for mounting.

The kit comes complete with Step by Step instructions and all parts including cut to length coaxial cable, the pre-drilled fibreglass tube outer casing, alloy mounting tube, heat shrink tubing and waterproof tip.

This antenna kit would make a great project for a club evening construction evening. The price is very reasonable at $40.00 plus another $15 P&P within NZ. You can pay via Direct Credit or by cheque or by cash.The NARC has a limited number of these for sale.
