Default Walkie talkie antennae

On 27.385mhz how well would a ⅛ wave (51.25 inches) antenna work on a cb radio walkie talkie compared to a cobra ha-ta (27 inches) antenna?

A 4-foot magnet-mount antenna on the roof of a vehicle with a 4-watt hand-held does as well as most other legal CB radios out there, with a range of maybe five miles or so in good conditions. That's basically what I have on my sedan for use on long highway trips (although not using a hand-held), listening for and giving traffic info when needed, e.g. traffic holdups, wrecks, etc that warrant consideration of immediate rerouting.

The problem comes when the antenna is attached just to the hand-held radio: it's pretty unwieldy to carry a 4-foot antenna, and the ground plane is terrible, resulting in a useful range probably a mile or less. It would probably range better than a 27-inch antenna, but still not good for most purposes.

I use my walkie talkies for DXing on mountain tops.

A loaded 1/4 wave whip in the 50in range will work a lot better than a shorter 27in version and I use a base loaded telescoping whip about that size with good results. I talked from So Cal to the UK on a 5W SSB walki takli with a 50in whip on the radio.

If you are considering an actual 1/8 wavelength, non loaded whip that will not match to the radio and will not work very well.

Good point. Years ago, I built an "L" dipole antenna for my WT. 102 inches vertically, and 108 inches horizontally. Made a huge difference in my range!

If you are trying to DX from mountain tops, you can also make a dipole wire antenna. Might be a better performer, and it's easy enough to do.

I have a Ĺ wavelength dipole for my new house in New Hampshire. I could easily hook it up to the walkie talkie... that would be a hoot.
