Re: C Crane Twin Ferrite Antenna

Hi Jay:

I agree - the Q Multiplier is a huge step up for picking things out of tough situations. I see the equality in terms of bare sensitivity, not selectivity, unless one applies feedback to the Twin Coil to get it to regenerate as well.

I purchased one of the C Crane Twin Ferrite antennas at a bargain price
and am eagerly awaiting its arrival. Does anyone on the list have
experience with one? Jay Allen at has a favorable opinion
of them but I'd still like to hear from someone on the list who may have
experience also. I'm sure I'll enjoy playing with it.
I've had one for quite a few years. It's a good antenna; certainly a major
improvement over the antenna in almost any ultralight. I think the
suggested retail price is a tad on the high side. Since you got it at a
bargain price, that's not an issue.

I would disagree with Kevin in regards to the Quantum Loop. The CCrane
antenna is easier to tune, but, IMHO, the Q-multiplier on the Quantum Loop
is a huge plus. It will let you pull signal out of noise in situations
where nothing else will work. This can be particularly important with ULRs
where you usually have limited or no choice of filters and no side band

I'd put it this way. The CCrane antenna is going to get you about 90% of
what you can possibly get with an indoor antenna. The Quantum Loop is going
to take you to 98%.

I'm sure you'll enjoy your new antenna. It should open up a whole new level
of reception.
