This project is about a cheap way of building a colinear antenna for VHF 145MHz, and having about 10dB more gain than that little 1/4-wave magmount

homebrew an helix antenna for 435 MHz by VE2ZAZ

The Super J Pole antenna is a co-linear vertical consisting of a number of half wave length vertical elements separated with half-wave length stubs (Tuning stub) feed with a folded matching stub by vk6ysf

This low power transmitter is developed for ARDF exercising purposes but of course can be used as super QRP transmitter either. With 1 or 2 meter wire as antenna and a ARDF receiver with ferrite-rod antenna the range is about 100m but with better antennas and a 'real' receiver the range is probably much larger.

This short dipole antenna has been described by Nadisha, 4S7NR and may be of interest to anyone wishing to get on 80M (3.5MHz) that have limited space available.

A 915 MHz four bay j-pole antenna plan

The Patch Antenna Array was constructed and used for various satellite up and down links at my previous residence in Melbourne, Victoria from 2003 - 2007

Amateur radio operators often document their station activities, equipment, and on-air experiences through personal blogs. These platforms serve as a digital logbook, sharing insights into antenna setups, radio modifications, and DX contacts. Such blogs frequently feature photographs of the shack, descriptions of operating conditions, and reflections on various aspects of the hobby, including contesting or portable operations. The PBG Station Brunei blog provides a glimpse into the amateur radio scene from Southeast Asia. It covers general station updates, local repeater information, and personal reflections on radio operations. The content offers a localized perspective on ham radio activities within Brunei, including details about specific frequencies and equipment used for local communication.

Homemade receiver for 80 meters band. The receiver works very well (in fact better than some of its successors), especially the AGC makes listening to 80m QSOs a real pleasure. Sensitivity is not cutting-edge, but on a full-size short-wave antenna it is by fare sensitive enough.
