Dexter M. Toyado "Design and Implementation of A VHF Tri-Loop Antenna for 2-Meter Amateur Band" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-3 | Issue-6, October 2019, pp.481-485, URL: https://www.ijtsrd.com/papers/ijtsrd28120.pdf

This paper presents the design and implementation of a triangular loop antenna using aluminum tubing of diameter 10mm with high electrical conductivity and reflecting ability. The antenna operates in very high frequency (VHF) band covering a frequency range of 140 to 150MHz. It has a gain of 3 dB and a radius of coverage of about 100 kilometers. It was constructed as a prototype antenna and tested at the author home base (QTH) with grid locator of PK23CO, where signals from DW4PGS, DW4PLN, DW4GSV, and DV4RBC were received with sharp audible sound(Q5) and full signal strength(S9). Better receptions were recorded for PD03, KB912-19, and KB951 –B157 on days with good propagation. Measurement result shows that the proposed antenna can work properly and meet well to be used in as reliable low cost homebrew effective VHF wide band antenna and it is an omnidirectional antenna.
