While I’ve not ruled out making a portable beam antenna, I’m having to stick with my 1/2 wave telescopic on my HT and my homemade 1/2 wave open dipole on the end of 2 metres of RG58 (both vertically polarised, I’m FM only).
While I’ve been able to do quite well at activating I’m aware that my simple dipole has no balun, so my SWR is going to be around 1.5:1, assuming I got the dimensions right.
How much of a problem is that for a 5W HT (Kenwood F7E)? Is it small enough to not worry about? The radio seems to not mind, I’ve had no issues. But it’s wasted power.
Assuming I should fix it, I looked at hairpin matches for beam antennas. Are they suitable for dipoles too? If not is there a simple alternative? I’ve not many tools to hand sadly, but can maybe borrow some workspace at work.
