Matt: Here is a copy of a statement on the Mosley web page . "Use of a Balun or Not We do not require the use of a balun. It is not needed" I believe that the Yagi Test book states that each antenna
Once in a while, the old "Proof-Reader" syndrome kicks in on me. In the post below, look at the phrase after "K7LXC". Talk about an appropriate miss-spelling! Bill--W4BSG Thank, everyone offered grea
Exactly the opposite. The peak gain of a dipole is 2.2 dBi. So a gain specification of 4 dBd is equivalent to 6.2 dBi. I suspect if you used a good line choke at the coax feed point and subtract 2.1d
Except that as far as I know Mosley never did adjust their inflated claims. On the other hand, as an owner of two Optibeam antennas (OB2-40 and OB16-3), I have considerable confidence that the claime

but none of the hardware is there. No u-bolts, no spacer blocks, nothing. Mosley advises that it's going to be about 300 dollars for all of the hardware. Given its lackluster performance in the test
Actually, I was mistaken - it is a Mosely Classic 36. I went out and spread everything out, measured, and verified in the manual this time. Something tells me that the answer is the same... :-) I've
Great Point Steve-I have an old pre-MFJ HyGain 205BA that I used for years. The instruction book for it states that it has 9.4 dbd of gain. Realistically I think modeling shows it to be around 6dbd o
IMHO the 34 and 36, if restored to original working order, are a much better choice that the "pro" models. 73 John N5CQ Actually, I was mistaken - it is a Mosely Classic 36. I went out and spread eve
There are compromises on all antennas, especially with multiband beams. Interlaced elements have no trap losses and are designed for optimum element spacing with minimal interaction from the non reso

I like my Force12 C-4XL (40/20/15/19m yagi). There are 2 elements on each band. 10m uses two driven elements, IME to have low VSWR across the band. It is an interlaced design, using mutually-coupled
