VHF Dipole Antenna Length Calculator - 3ROAM
The VHF (Very High Frequency) range is 30 MHz to 300 MHz. Use this calculator to find the dimensions of a Dipole antenna designed to operate at this frequency range. A half-wave dipole antenna is comprised of two quarter-wavelength conductors placed end to end .
What Is the Ideal VHF Antenna Length? - Metz Antennas
2020年4月29日 — Considering how important getting the right VHF antenna length is, it’s no surprise that there’s a clear-cut guide for choosing the right size antenna. The wavelength of a signal should always be 1/4 the length of the antenna you’re …
Everything you need to know about your VHF antenna
2023年9月27日 — Antenna length vs wavelength. The dimensions of the antenna are key. Operating at 156-162MHz, maritime VHF bands have a wavelength between 1.72m and 1.92m (the distance between peaks). There is a relationship between this wavelength and the antenna length, which means that VHF aerials range from about 25cm up to 5-6m.
Ham Radio HF/VHF Antenna Lengths Chart. - hamuniverse.com
Here is a handy chart for determing 1/4 wave verticals, 1/2 wave dipoles, and full wave loop lengths. All antenna lengths in the information below are in feet and are the results based on the standard formula of 468 / FMhz = total length in feet. Loop antenna lengths are based on using 1005 / FMhz = total loop length in feet.

Dipole Antenna Length Tests - The Solid Signal Blog
2020年3月26日 — The idea for this blog is to test the best length for a dipole antenna for TV reception. When transmitting, as mentioned in the last blog, https://blog.solidsignal.com/tutorials/cleartv-mini-antenna-tests-sort-of/ it is best to keep the antenna length to what is needed to keep the transmitter safe …
Dipole Calculator | Antenna Length Calculator
2024年7月30日 — Our dipole calculator is a simple tool that allows you to compute the length of a simple antenna — it'll also provide you with the value of the wavelength and the adjustment factor [k].
Optimal length of HT antenna for VHF UHF and diminishing return
The optimal length for a HT whip antenna would be ¼ λ. The smaller rubber ducky, with its comparable performance, would win hands down for its convenience and ease of use. The performance of either would be enhanced by adding a ¼ λ flexible-wire counterpoise, popularly known as a 'rat tail' or 'tiger tail'.

Build your own inexpensive, easy, high-performance VHF/AIS antenna
Another commonly seen VHF antenna is about 8 feet long and usually mounted on the stern rail; it has more gain than the shorter masthead antenna but is also more directional (i.e. one loses signal strength when heeled over).
