Walkie-Talkies

Moxon antenna calculator: dimensions, plans, and tuning guide. Use this Moxon antenna calculator to generate the A–E dimensions for a classic 2-element Moxon rectangle from your design frequency and conductor diameter. Choose common amateur-radio bands or enter a custom frequency, then use the plans, construction notes, tuning steps, gain and radiation-pattern guidance below to turn the calculated geometry into a practical antenna.

Calculate the vertical and horizontal wire lengths for a half-square antenna, choose a corner-fed or end-fed configuration, and use the results as practical starting dimensions for building and tuning your antenna.

Calculate the wire length, side dimensions, loop height, wavelength, and quarter-wave matching section for a delta loop or other full-wave loop antenna. Enter your operating frequency, choose the loop geometry, and use the calculated dimensions as a practical starting point for construction and tuning.

EFHW antenna calculator: end-fed half-wave design and length

OCFD Dimensions, Design & Plans. Calculate the total length, short leg, long leg and feedpoint position for an off-center-fed dipole. Choose a band or custom frequency, select the OCF split, and use the results as a starting point for building and tuning your antenna.

Calculate section lengths for a multiband linked dipole, standard dipole, or inverted-V antenna by frequency. Enter the HF bands or exact operating frequencies you want to use. The calculator returns the starting cut length for each dipole leg, individual linked sections, link positions, and the complete active antenna length for every band. Linked dipole geometry […]

Baofeng has completely disrupted the two-way radio market. What was once an expensive hobby reserved for those with deep pockets is now accessible to everyone. Whether you are a prepper building your “go-bag,” a hiker wanting peace of mind, or a radio enthusiast looking to dive into the world of repeaters, there is a Baofeng […]

Climbing in the mountains is as much about managing risk and communication as it is about strength and technical skill. In many cases, your phone won’t work. A good walkie-talkie (or two-way radio) can be a lifeline: for coordination between climbing partners, alerting in emergencies, coordinating when one rope team is out of sight, or […]

Heading out for a hike and want to stay connected with your group, even where cell service is a distant dream? A walkie talkie is your trusty sidekick! Unlike your smartphone, which might give up in the wilderness, walkie talkies keep you in touch on trails, in mountains, or deep in the forest. But how […]

When you’re out backpacking, staying connected is a big deal, whether you’re trekking with buddies or going solo. Walkie talkies are a solid choice for keeping in touch and staying safe on the trails. But with so many models out there, picking the right one can feel like a hassle. So, I’ve dug into the […]
